Specialist Waterproofing Solutions — Brisbane &amp; Gold Coast
Innovare Waterproofing delivers membrane application, crack injection, leak sealing and remedial waterproofing for residential, commercial and industrial properties across Brisbane, the Gold Coast and greater South East Queensland. We hold current QBCC and NSW builder’s licences, carry full public liability and professional indemnity insurance, and back every job with written warranties aligned to Australian Standards AS 3740 and AS 4654.
The Water Is Getting In. We Stop It.
Water ingress is rarely a minor inconvenience. Left unaddressed, it destroys structural steel, spalls concrete, breeds mould and creates expensive liability for body corporates, developers and homeowners alike. Brisbane and Gold Coast’s subtropical climate — intense summer storms, high ambient humidity and rapid thermal cycling — accelerates the degradation of failing waterproofing systems faster than almost anywhere else in Australia.
Innovare Waterproofing was founded to solve exactly this problem. We specialise in the diagnosis, specification and application of waterproofing systems across every substrate and every application type — from a single bathroom in Newstead to a podium car park in Broadbeach. Our team carries hands-on experience across hundreds of residential, strata and commercial projects throughout South East Queensland.

Frequently Asked Questions
Q: Do you work on both new construction and existing buildings? Yes. We apply waterproofing membranes on new-build projects for builders and developers, and we carry out remedial waterproofing on existing structures where systems have failed or where new water ingress has been detected. Both streams require different diagnostic and specification approaches, and our team is experienced in both.
Q: Are you licensed to perform waterproofing work in Queensland? Yes. We hold a current QBCC licence that covers waterproofing trade contractor work in Queensland, as well as a NSW builder’s licence. All work is carried out or directly supervised by licenced tradespeople.
Q: How quickly can you assess a leak? For urgent commercial situations or active leaks causing damage, we aim to attend within one to two business days in the Brisbane and Gold Coast metro areas. For standard inspection and quotation appointments, typical lead times are three to five business days depending on current workload.
Q: Do you provide waterproofing inspection certificates? Yes. For bathroom and wet-area installations we provide written inspection certificates confirming compliance with AS 3740, suitable for private certifiers, council building inspectors and building surveyors.

About Innovare Waterproofing
Innovare Waterproofing is a QBCC-licensed waterproofing specialist serving Brisbane, the Gold Coast and greater South East Queensland. We deliver membrane application, crack injection, remedial waterproofing and concrete repair for residential, commercial and industrial clients — backed by manufacturer accreditations, written warranties and compliance with Australian Standards AS 3740 and AS 4654.
Who We Are
Innovare Waterproofing is a specialist division of the Innovare Group — a single licensed builder operating multiple project-specialist brands across Queensland and New South Wales. The Innovare Group structure means our clients receive the commercial capability and insured accountability of a licensed builder, combined with the focus and technical depth of a dedicated waterproofing trade contractor.
We were established to address a gap in the Queensland market: property owners, strata managers and builders increasingly encountered waterproofing “specialists” who were, in practice, generalist trades with limited membrane system knowledge, no manufacturer accreditation and no documented methodology. The outcomes were predictable — systems that failed early, disputes about liability and costly rectification work.
Innovare Waterproofing was built differently. Our team comprises experienced waterproofing applicators with backgrounds across residential renovation, multi-storey commercial construction and industrial remedial works. We invest in manufacturer accreditation, ongoing product training and documented installation methodology because we believe the quality of waterproofing work should be verifiable — not taken on faith.
Our Experience
Our team has completed waterproofing projects across every major application category in the SEQ market:
Residential wet areas — bathrooms, ensuites, laundries, shower bases and balconies in houses, townhouses and strata complexes throughout Brisbane’s inner suburbs and the Gold Coast.
Strata and body corporate remediation — investigating and rectifying waterproofing failures in multi-storey residential buildings, including podium deck remediation, below-ground carpark waterproofing and facade remediation.
Commercial new construction — working alongside principal builders on shopping centres, commercial office buildings and industrial facilities to apply waterproofing systems to specification and within construction programme constraints.
Industrial and infrastructure — concrete crack injection, active leak sealing and joint repair in water treatment facilities, tunnels, basement carparks and retaining structures.
Below-ground and basement works — tanking and cavity drain systems for residential and commercial basements, undercroft spaces and subterranean car parks.
South East Queensland presents specific waterproofing challenges that our team understands well. The subtropical climate delivers intense summer rainfall, high humidity and significant thermal cycling that accelerates membrane fatigue and sealant breakdown. Older housing stock in inner Brisbane suburbs such as Paddington, New Farm and Woolloongabba often presents rising damp and failed original damp-proof courses. The high-density apartment construction that transformed the Gold Coast over the past three decades has produced a large cohort of ageing buildings now entering their first and second major remediation cycles.

Australian Standards and Technical Compliance
Every wet-area waterproofing installation is designed and installed to comply with AS 3740 — Waterproofing of Domestic Wet Areas. We provide written inspection records documenting compliance for each project.
External above-ground membrane systems — including balconies, terraces and roof decks — are specified and installed to AS 4654.2 — Waterproofing Membranes for External Above-Ground Use. This standard governs substrate preparation, membrane selection, lap dimensions, termination methods and protection requirements.
Our team is familiar with the requirements of the National Construction Code (NCC/BCA) as they relate to waterproofing, and with the waterproofing-related provisions of the Queensland Development Code.
Manufacturer Accreditations and Partnerships
We maintain applicator accreditation with leading waterproofing product manufacturers. Accreditation provides:
Direct access to manufacturer technical representatives for specification support
Training on the current product range and application methodology
The ability to offer manufacturer-backed system warranties on qualifying projects
Priority access to technical data sheets, application guides and product safety information
Ask us about manufacturer warranty options when requesting a quote — for qualifying new-construction and large-scale remedial projects, extended manufacturer warranties may be available.
Our Approach: Diagnose Before You Apply
Many waterproofing failures in SEQ result not from poor-quality products but from misdiagnosis. Water tracks. The visible damage — a wet ceiling, a mouldy wall, staining on a soffit — is rarely directly below the point of water entry. Applying a new membrane without correctly identifying the entry point simply relocates the problem.
Our process begins with a thorough investigation: probing, thermal imaging where appropriate, pressure testing of drain assemblies and a systematic review of all penetrations, flashings and joints. Only once we have identified the failure mechanism do we specify the repair methodology. This approach produces more durable outcomes and fewer callbacks.
Learn more about our inspection process on our Waterproofing Inspections page.
Written Warranties
We provide written waterproofing warranties on all installations. Warranty terms reflect the system type, substrate condition, preparation methodology and project scope. We are transparent about what is and is not covered, and we honour our warranties without dispute.
Contact the Team
We welcome enquiries from homeowners, builders, property managers, body corporates, strata managers and facility managers throughout Brisbane, the Gold Coast and South East Queensland.

Remedial Waterproofing — Brisbane &amp; Gold Coast
Remedial waterproofing addresses failed or degraded waterproofing systems in existing buildings. Unlike new-construction waterproofing, remedial work requires thorough investigation to identify the true point of water entry before any membrane or injection system is applied. Innovare Waterproofing provides complete remedial waterproofing services for residential, strata and commercial properties across Brisbane, the Gold Coast and South East Queensland.
When Waterproofing Systems Fail
Waterproofing systems have finite service lives. The membranes, sealants, flashings and joint compounds installed during original construction eventually degrade — and when they do, water finds its way into the building fabric. In South East Queensland’s subtropical climate, the combination of UV exposure, thermal cycling, intense rainfall and high humidity accelerates this process significantly compared to more temperate climates.
Common failure mechanisms in SEQ buildings include:
Membrane delamination — adhesive bond between membrane and substrate breaks down, allowing water to migrate laterally beneath the membrane before penetrating the building.
Sealant joint failure — silicone and polyurethane sealants harden, crack and debond at penetrations, perimeter flashings and movement joints, creating open pathways for water.
Balcony and terrace membrane fatigue — exposed membranes are subjected to UV radiation, foot traffic and thermal movement. After 10–15 years, even well-installed systems may require renewal.
Substrate cracking — concrete slab cracking from structural movement, shrinkage or impact breaks through the membrane above it, creating direct water paths.
Drain and outlet failure — blocked, displaced or incorrectly installed drainage outlets back water up against perimeter flashings, overwhelming the membrane system.
Original non-compliance — many buildings constructed prior to the current versions of AS 3740 and AS 4654 have waterproofing systems that were never fully compliant. As these age, failures emerge more readily.
The Investigation Process
Correct diagnosis is the most important step in any remedial waterproofing project. Water travels. The leak in a lower-floor ceiling is rarely directly below the actual entry point — water may track laterally for metres along rebates, conduit penetrations or over membrane laps before finding a downward path.
Our remedial investigation process typically includes:
Visual inspection of all suspect areas — drains, penetrations, flashings, joints, cracks and exposed membrane surfaces.
Hose/flood testing of suspect areas to establish which surfaces are contributing to the ingress.
Probing and opening up of finished surfaces where necessary to inspect membrane condition and substrate.
Drain testing — checking fall, blockage and outlet seal condition.
Written investigation report detailing findings, failure causes and recommended remediation approach, with photographs.
This report is provided to the client before any remediation works commence. It forms the basis of the scope of work and the written warranty.
Remediation Methods and Systems
Depending on the investigation findings, remediation may involve one or more of the following approaches:
Full Membrane Replacement Where the existing membrane has failed beyond patch repair, complete removal and replacement with a new system is the appropriate response. This provides the longest-lasting outcome and allows a full substrate inspection and preparation prior to installation.
Crack Injection Structural or leaking cracks in concrete are sealed using epoxy (structural) or polyurethane (flexible/leaking) injection. See our Crack Injection page.
Polyurethane and Silicone Joint Resealing Failed sealant joints at perimeters, penetrations and movement joints are raked out, primed and resealed with appropriate sealant systems.
Liquid-Applied Membrane Overlay Where the substrate is sound and the existing membrane is securely bonded but porous or cracked at the surface, a liquid-applied membrane overlay may provide a cost-effective solution — subject to investigation findings.
Cementitious Crystalline Treatment For below-ground and basement structures where access is limited to the positive or negative (wet) face, cementitious crystalline waterproofing systems can be applied to seal water entry. See Concrete Leak Sealing.
Remedial Waterproofing for Strata and Body Corporate Properties
Multi-storey residential buildings in inner Brisbane and the Gold Coast are significant consumers of remedial waterproofing services. Ageing apartment buildings — many constructed in the 1980s, 1990s and 2000s — are now well past the original service life of their waterproofing systems.
We work closely with body corporate managers, strata committees and their consultants to:
Conduct building-wide waterproofing condition assessments
Provide detailed defect reports and remediation specifications
Stage remediation works to minimise disruption to residents
Provide progress documentation and completion reports suitable for BCCM-regulated records
Cost Factors in Remedial Waterproofing
Remedial waterproofing costs vary significantly based on:
Access and preparation — removing tiles, screeds or overlaid finishes is often the largest cost component.
Extent of damage — the area of substrate that requires treatment after failed membrane removal.
System selection — the specification requirement for a particular system (e.g. traffic-bearing versus pedestrian membrane, exposed versus protected).
Height and access — working at height requires scaffolding, EWP hire or rope access, all of which add cost.
Urgency — emergency attendance for active damage control carries a premium.
We provide transparent, itemised written quotes following investigation. We do not provide ball-park figures without first understanding the full scope.

Frequently Asked Questions
Q: Can you fix a waterproofing problem without removing the tiles? Sometimes, but not always. Where the failure is isolated to a joint, penetration or small crack area, targeted repairs without full tile removal may be feasible. However, if the membrane itself has failed across a significant area, attempting repair without tile removal typically results in a short-lived outcome. We will always tell you honestly whether a partial repair is appropriate or whether full replacement is the correct scope.
Q: How long does remedial waterproofing last? A correctly diagnosed and installed remedial waterproofing system should last as long as a new-installation system — typically 10 to 25 years depending on the system type, substrate condition and the level of ongoing maintenance. We provide written warranties commensurate with the system installed.
Q: Who is responsible for waterproofing failures in a strata building? Liability for waterproofing failures in strata schemes depends on the location of the failing element (lot versus common property) and the cause of the failure. In general, waterproofing membranes within wet areas of individual lots are the lot owner’s responsibility, while external membranes, roofs, podium decks and building envelopes are common property. We can provide defect reports suitable for use in BCCM disputes or insurance claims.
Q: Do you work interstate? Our primary service area is Queensland. We hold a NSW builder’s licence and can undertake projects in New South Wales on a project-by-project basis. Contact us to discuss your requirements.

Commercial Waterproofing — Brisbane &amp; Gold Coast
Innovare Waterproofing delivers specialist waterproofing systems for commercial buildings, multi-storey residential developments, retail centres and industrial facilities across Brisbane, the Gold Coast and South East Queensland. We work directly with builders, developers, facility managers and body corporate managers to apply and remediate waterproofing systems on every element of the commercial building envelope.
Commercial Waterproofing Applications
Shopping Centres and Retail Precincts Retail environments present complex waterproofing challenges — high foot traffic, demanding substrate conditions, and the need to maintain trading while works are in progress. We apply traffic-bearing membrane systems to concourses, external plazas and service areas, and carry out leak investigations and remediation on roofs, plant rooms and below-grade areas with minimal disruption to tenants.
Multi-Storey Apartment Buildings Multi-storey residential developments — from three-storey walk-ups in inner Brisbane suburbs to high-rise towers on the Gold Coast foreshore — require waterproofing across multiple elements: bathrooms, laundries, balconies, podium decks, basement carparks, planters and roofs. We work with developers and builders during construction, and return for remedial works as buildings age and initial systems require renewal.
Podium Decks Podium decks — the concrete slabs that form the roof of basement carparks and the base of landscaped courtyards in multi-storey buildings — are among the most technically demanding waterproofing applications in commercial construction. They bear structural loads, are subjected to root penetration from landscaping, and must remain trafficable and watertight for decades with minimal maintenance access.
We apply sheet membrane and liquid-applied systems to podium decks with appropriate drainage design, root barrier systems and screed/topping protection to suit the planned finish.
Car Parks and Basement Structures See our dedicated Car Park Waterproofing and Basement Waterproofing pages.
Industrial and Infrastructure Facilities Water treatment plants, pumping stations, tanks, tunnels and retaining structures require waterproofing systems suited to constant hydrostatic pressure, aggressive chemical environments and long service-life expectations. We apply cementitious crystalline, polyurethane and epoxy systems to these structures.
Working With Principal Contractors
We understand the demands of working as a waterproofing subcontractor on commercial construction projects. We provide:
SWMS and site induction documentation prior to commencement
Inspection and test plans (ITPs) for hold-point verification by the principal contractor or building surveyor
Progress reporting aligned to the principal’s programme
Defect-free completion certificates and as-installed records
Manufacturer technical representative attendance for specification-critical elements
Our team is familiar with working in active construction environments and complies with all site-specific safety requirements.
Compliance and Documentation
Commercial waterproofing projects typically require formal compliance documentation. We provide:
Written inspection records for each application stage
Certificates confirming compliance with AS 3740 (wet areas) and AS 4654.2 (external above-ground membranes)
Material data sheets and product approvals for all applied systems
Written waterproofing warranties for the installed system

Frequently Asked Questions
Q: Can you work on live sites with active tenants or residents? Yes. We are experienced in working on partially occupied buildings and active retail environments. We use low-odour products where feasible, manage access with body corporate or facility management, and stage works to minimise disruption.
Q: Do you provide manufacturers’ system warranties on commercial projects? Yes, on qualifying projects and for qualifying system types. Manufacturer-backed system warranties require the use of an accredited applicator (which we are), use of the full manufacturer system, and installation within specification. Ask us at quotation stage about warranty options for your specific project.
Q: How do you handle waterproofing documentation for NCC compliance? We provide written installation records, inspection certificates and compliance statements referencing the relevant Australian Standards and NCC provisions. These documents are suitable for private certifiers, building surveyors and development approval conditions.
Q: Are you able to carry out condition assessments and specify remedial works for a body corporate? Yes. We provide building-wide waterproofing condition assessments, written defect reports with photographic evidence, and remediation specifications — all of which can be used by body corporate committees when tendering remedial works. We can also carry out the remedial works ourselves if appointed.

URL Slug: /residential-waterproofing Primary Keyword: residential waterproofing Brisbane Secondary Keywords: bathroom waterproofing Brisbane, balcony waterproofing Gold Coast, laundry waterproofing QLD, AS 3740 waterproofing Brisbane
Residential Waterproofing — Brisbane &amp; Gold Coast
Innovare Waterproofing installs and remediates waterproofing systems for houses, townhouses and apartments across Brisbane and the Gold Coast. Every wet-area installation is specified and applied to AS 3740, with written inspection records available for building certification. We serve owner-occupiers, landlords, renovators and developers across South East Queensland.
Why Residential Waterproofing Matters in SEQ
South East Queensland’s climate is hard on residential waterproofing. Summer storms deliver intense, concentrated rainfall. High ambient humidity keeps substrates damp for extended periods. Thermal cycling — particularly on north-facing balconies and roof decks — accelerates membrane fatigue. And the high density of apartment and townhouse living in inner Brisbane and Gold Coast suburbs means that a waterproofing failure in one lot quickly becomes a neighbour’s water ingress problem.
Getting waterproofing right the first time — with correct system selection, proper substrate preparation and compliant installation — is significantly cheaper than rectification.
Residential Waterproofing Services
Bathroom and Ensuite Waterproofing Showers, wet areas and floor-to-ceiling applications in compliance with AS 3740. We provide inspection certificates for private certifiers and building surveyors. See Bathroom Waterproofing.
Laundry Waterproofing Laundry floors, walls and sinks — properly waterproofed laundries prevent costly structural damage and mould in adjacent spaces.
Balcony Waterproofing Membrane systems for residential balconies — liquid-applied and sheet membrane options with appropriate falls, drainage and tile-over finishes. See Balcony and Terrace Waterproofing.
Retaining Wall Waterproofing Retaining walls, particularly in Brisbane’s hilly suburbs, are subject to sustained hydrostatic pressure. We apply tanking and drainage systems to the retained face to prevent water migration into adjacent structures.
Sub-Floor Waterproofing and Vapour Barriers For homes with sub-floor spaces — common in older inner-Brisbane suburbs — we apply vapour barriers and tanking systems to control ground moisture and rising damp. See Rising Damp Treatment.
Below-Ground Basement Waterproofing See Basement Waterproofing.

Frequently Asked Questions
Q: Do I need a waterproofing certificate for a bathroom renovation? In Queensland, waterproofing of wet areas is a regulated activity under the QBCC Act. A licensed waterproofer must install the membrane, and a written inspection certificate must be provided. This is required for building certification and is important for insurance and resale purposes.
Q: How long does residential waterproofing take? A standard bathroom or ensuite waterproofing application — substrate preparation, two membrane coats and inspection — typically takes one to two days, followed by a curing period of 24 to 48 hours before tiling can commence. Larger or more complex projects take proportionally longer.
Q: Can I waterproof over existing tiles? Generally no. For a compliant and durable outcome, the membrane must be applied directly to the structural substrate (concrete or fibre-cement sheet). Tiling over an existing membrane without removing the tiles and verifying the substrate condition produces a non-compliant and usually short-lived result.
Q: What warranty do you provide on residential waterproofing? We provide written warranties on all residential waterproofing installations. Warranty periods vary depending on the system applied and the substrate condition. We will specify the warranty term in your written quote.
Page 6: Concrete Protective Coatings
Meta Title: Concrete Protective Coatings Brisbane &amp; Gold Coast | Innovare Meta Description: Anti-carbonation coatings, corrosion inhibitors and concrete sealers for Brisbane and Gold Coast structures. Extend service life. QBCC licensed applicators. URL Slug: /concrete-protective-coatings Primary Keyword: concrete protective coatings Brisbane Secondary Keywords: anti-carbonation coating QLD, concrete corrosion protection Brisbane, concrete sealer Gold Coast, concrete repair and protection SEQ
Concrete Protective Coatings — Brisbane &amp; Gold Coast
Concrete protective coatings extend the service life of concrete structures by blocking the ingress of carbon dioxide, chlorides, water and aggressive ions that cause carbonation, reinforcement corrosion and structural deterioration. Innovare Waterproofing applies anti-carbonation coatings, corrosion inhibitor systems and concrete sealers to residential, commercial and infrastructure assets across South East Queensland.
Why Concrete in SEQ Needs Protection
Concrete appears robust but is inherently porous. In South East Queensland’s coastal and subtropical environment:
Carbonation — atmospheric CO₂ dissolves in pore water, progressively lowering the pH of the concrete and eventually destroying the passive protection of reinforcing steel. Carbonation rates are accelerated in warmer, humid climates.
Chloride ingress — coastal properties within kilometres of the ocean are exposed to airborne chloride ions that penetrate concrete and initiate rebar corrosion. Gold Coast and Bayside Brisbane properties are particularly at risk.
Moisture cycling — wetting and drying cycles drive soluble salts and aggressive ions deeper into the concrete matrix over time.
The result — rust staining, concrete spalling, delamination and ultimately structural capacity reduction — is highly visible and very expensive to repair. Anti-carbonation coatings and concrete sealers applied proactively, or as part of a remediation programme, significantly extend structural service life.
Our Concrete Protective Coating Systems
Anti-Carbonation Coatings Elastomeric acrylic and polyurethane anti-carbonation coatings form a flexible, breathable film over the concrete surface that blocks CO₂ and water vapour ingress while allowing moisture vapour to pass outward from the substrate. These systems bridge hairline cracks and provide UV-stable colour finishes.
Chloride Barrier Coatings For coastal structures, silane-siloxane penetrating sealers and barrier coatings provide deep-penetration chloride exclusion. These products react within the concrete matrix to create a hydrophobic zone that resists chloride ingress without altering the surface appearance.
Corrosion Inhibitors Where reinforcement corrosion has already initiated, migrating corrosion inhibitor systems can be applied to the concrete surface and penetrate to the rebar level, stifling the electrochemical corrosion reaction and extending the structure’s service life.
Concrete Sealers — Industrial and Commercial Floors Epoxy, polyurethane and acrylic sealers for factory floors, car park decks and commercial concrete surfaces — providing abrasion resistance, chemical resistance and moisture exclusion.
Application Areas
Parking structures, retaining walls, bridge abutments, seawalls, façades, balcony soffits, rooftop plant room floors, industrial flooring, water tanks and infrastructure assets throughout Brisbane and the Gold Coast.

Frequently Asked Questions
Q: How do I know if my concrete needs an anti-carbonation coating? The first indicators are rust staining on the concrete surface, visible cracking or spalling, and delaminating concrete revealing corroded rebar. A simple phenolphthalein carbonation depth test can indicate how far carbonation has progressed. We can carry this out as part of a condition assessment.
Q: How long do anti-carbonation coatings last? Quality elastomeric coatings applied correctly on prepared substrates typically provide 10–20 years of protection, subject to UV exposure, foot/vehicle traffic and ongoing maintenance. Recoating the sacrificial surface layer before full coating breakdown provides continuous protection at lower cost than full replacement.
Q: Can protective coatings be applied to wet or damp concrete? No. Substrate moisture content must be within product tolerances before application. We test surface moisture content and, if required, schedule work around dry weather windows or apply primer systems designed for mildly damp substrates.
Q: Do protective coatings change the appearance of concrete? Penetrating silane-siloxane sealers are typically invisible on application. Film-forming coatings are available in a range of finishes from clear to full-colour opaque. We will discuss appearance requirements with you as part of the specification process.

Fast, effective, QBCC licensed. Get a free assessment. URL Slug: /crack-injection Primary Keyword: crack injection Brisbane Secondary Keywords: polyurethane injection Brisbane, epoxy crack injection QLD, concrete crack repair Gold Coast, structural crack repair SEQ
Crack Injection — Brisbane &amp; Gold Coast
Crack injection uses low-pressure epoxy or polyurethane resin to fill and seal cracks in concrete and masonry structures. Epoxy injection restores structural continuity to cracked concrete. Polyurethane injection seals actively leaking cracks and joints against water ingress. Innovare Waterproofing carries out crack injection assessments and treatments for residential, commercial and infrastructure assets across Brisbane, the Gold Coast and South East Queensland.
When Is Crack Injection Appropriate?
Not every crack in concrete requires injection. Hairline cracks below 0.2 mm width in a non-aggressive environment may be monitored without treatment. Crack injection is appropriate when:
Cracks are structurally significant and require restoration of section capacity
Cracks are admitting water into habitable spaces, basements or buried structures
Cracks in water-retaining structures (tanks, pools) are causing leakage
Surface crack repairs have previously failed due to ongoing movement
Cracks are creating pathways for carbonation, chloride or other aggressive agents
We assess every crack in context before recommending injection. Where a crack indicates underlying structural movement or ongoing settlement, we will advise on structural investigation before proceeding with injection — addressing the symptom without understanding the cause is rarely a durable solution.
Epoxy Injection — Structural Crack Repair
Epoxy resin injection is used for cracks where structural continuity needs to be restored. Epoxy resins have high tensile and compressive strength — once cured, the injected crack is typically stronger than the surrounding concrete.
The process: 1. Crack width and depth are assessed. Active movement is monitored before injection commences. 2. The crack surface is cleaned of dust, grease and contamination. 3. Injection ports are installed at regular intervals along the crack — typically every 150 to 300 mm depending on width. 4. The crack surface is sealed between ports with epoxy paste. 5. Low-pressure injection begins at the lowest or innermost port and proceeds until resin returns at the next port. 6. Ports are capped sequentially as fill is confirmed. 7. After curing (typically 24–48 hours), ports are removed and surface is finished.
Suitable substrates: Concrete columns, beams, slabs, walls, masonry, concrete tanks and retaining walls.
Polyurethane Injection — Active Leak Sealing
Polyurethane foam injection is used to seal actively leaking cracks, cold joints and construction joints in concrete and masonry. The expanding foam reacts with water present in the crack, creating a flexible, water-resistant seal that accommodates minor ongoing movement.
Hydrophilic versus hydrophobic foams: Hydrophilic polyurethane foams require water to react and swell — they are ideal for actively wet cracks. Hydrophobic foams react with ambient humidity and are used in drier conditions where flexibility and durability are the primary requirements.
Applications: Basement walls, underground carparks, tunnels, water tanks, sewage infrastructure, subterranean retaining walls and below-ground residential structures throughout Brisbane and the Gold Coast.

Crack Monitoring and Assessment
We offer crack monitoring services for ongoing or progressive cracking — photographic and crack gauge monitoring to establish whether cracking has stabilised before injection is carried out. Injecting an active crack without addressing the underlying movement simply re-opens the crack.

Frequently Asked Questions
Q: What is the difference between epoxy and polyurethane crack injection? Epoxy injection is used where structural restoration is required — it bonds the crack faces together and restores section capacity. Polyurethane injection is used primarily for waterproofing purposes — it seals against water ingress but does not restore structural continuity. The appropriate product depends on the purpose of the repair.
Q: Can crack injection be carried out from the dry side of a leaking wall? Yes. Polyurethane injection is typically carried out from the dry (interior) face of a structure. The resin travels through the crack toward the water source and expands on contact with water, sealing the crack progressively from inside outward.
Q: Will the crack come back after injection? Epoxy injection of a stabilised crack provides a durable repair. If the underlying cause of cracking (e.g. ongoing settlement, thermal movement, structural loading) has not been addressed, new cracking may develop adjacent to the injected area. We always assess the cause of cracking before recommending injection.
Q: How long does crack injection take? Most residential crack injection works are completed in a single day. Commercial or infrastructure projects with large numbers of cracks or complex access requirements may take longer. We will provide a realistic programme estimate in our written quote.

Concrete Leak Sealing — Brisbane &amp; Gold Coast
Concrete leak sealing stops active water flow through cracks, joints and penetrations in below-ground and water-retaining structures. Using hydrophilic polyurethane, cementitious plugging compounds and crystalline systems, Innovare Waterproofing seals leaks in basements, underground carparks, tunnels, tanks and retaining structures across Brisbane, the Gold Coast and South East Queensland.
Active Leaks Require Specialist Treatment
When water is actively flowing through a crack or joint in a concrete structure, standard waterproofing membranes and sealants cannot be applied directly — the active flow prevents adequate adhesion and curing. Specialist active leak sealing products are specifically formulated to react in the presence of water, setting rapidly even under hydrostatic pressure.
Common active leak situations in SEQ structures include:
Basement carparks — construction joints, pipe penetrations and cracks in perimeter walls and floor slabs.
Below-ground retaining walls — water table ingress through cracked or poorly detailed poured concrete.
Water and sewage infrastructure — leaking joints in tank walls, chamber walls and tunnel linings.
Swimming pools and water features — leaking structural cracks and joint failures.
Undercroft and sub-floor spaces — ground moisture entering through floor slab cracks.
Leak Sealing Systems and Methods
Hydraulic Cement and Cementitious Plugging For high-flow point leaks, rapid-setting hydraulic cement compounds are used to create an immediate plug, stopping flow and allowing further treatment with injection or crystalline systems.
Crystalline Waterproofing Cementitious crystalline products penetrate the concrete matrix and react with moisture and free lime to grow insoluble crystals that block pores and capillaries. Crystalline systems self-heal minor future cracking in the presence of moisture, making them particularly well suited to below-ground water-retaining structures.
Hydrophilic Polyurethane Injection Hydrophilic polyurethane resin is injected into actively leaking cracks and construction joints. The resin reacts with water, expanding to fill the void and create a flexible, watertight seal. See also Crack Injection.
Sodium Bentonite Swell Strips and Grout Bentonite-based water stops are used at construction joints — they absorb water and swell to create a compressive seal within the joint. For existing joints where the original water stop has failed, bentonite grout injection provides a flexible remedial solution.
Below-Ground Structures and Groundwater
Brisbane and the Gold Coast have significant areas of high groundwater — particularly along the river and coastal floodplains. Below-ground structures in these areas experience sustained hydrostatic pressure that conventional membrane systems on the negative (interior) face struggle to resist. Leak sealing combined with effective below-ground drainage (cavity drain systems, sump pumps) provides a robust, integrated solution for these conditions.
See Basement Waterproofing for more on below-ground waterproofing system design.

Frequently Asked Questions
Q: Can you seal a leak that has active water flowing through it? Yes. This is specifically what concrete leak sealing products are designed to do. Hydraulic cement and hydrophilic polyurethane systems are designed to set and seal under active flow conditions. We assess flow rate and water pressure as part of our approach selection.
Q: How long do leak sealing repairs last? Correctly installed crystalline and injection systems provide long-term sealing. Crystalline systems in particular have excellent durability because the crystals are formed within the concrete matrix rather than on the surface. However, if the underlying structural condition (cracking, settlement) is ongoing, future maintenance may be required.
Q: Is crystalline waterproofing suitable for potable water tanks? Yes. A number of leading crystalline waterproofing products carry approvals for use in potable water contact applications. We can specify and apply these products for water tanks, reservoirs and swimming pools. Confirm the specific product approval with us when enquiring.
Q: Do you provide emergency call-out for active leaks? We aim to respond to urgent commercial situations as quickly as possible — typically within one to two business days in the Brisbane and Gold Coast metro areas.

Joint Repair — Movement and Construction Joints
Joint repair covers the replacement or repair of failed sealant systems at movement joints, construction joints, control joints and perimeter flashings in buildings and civil structures. Correct joint design and sealant selection are critical to building envelope performance. Innovare Waterproofing carries out joint repair and replacement for residential, strata and commercial properties across Brisbane, the Gold Coast and South East Queensland.
Why Joints Fail
Every building contains joints designed to accommodate thermal movement, structural deflection and construction tolerances. These joints are sealed with flexible sealant systems — typically polyurethane or silicone — that deform with the joint movement while maintaining a watertight seal.
Sealants fail for predictable reasons:
Age and UV degradation — most sealants have a service life of 10 to 20 years under UV exposure. Hardening, chalking, cracking and debonding are the visible signs.
Wrong sealant selection — applying the incorrect sealant product (e.g. using a non-movement silicone at an expansion joint) results in premature adhesion failure.
Incorrect preparation — failing to prime substrates, leaving dust or oil contamination, or applying to moist surfaces results in early adhesion failure.
Joint design errors — joints too narrow, too shallow or without appropriate backer rod cannot perform as required regardless of sealant quality.
Oversized joints — joint movement exceeding the sealant’s elongation capacity causes fatigue cracking.
Joint Repair and Replacement Process
Assessment: We inspect all joints, document their condition and identify specific failure modes.
Preparation: Failed sealant is fully removed using mechanical cutting, grinding or raking — partial raking of live sealant over old material never provides an acceptable bond life.
Backer rod installation: Correctly sized closed-cell polyethylene backer rod is installed to provide the correct sealant depth, prevent three-sided adhesion and support the sealant geometry.
Priming: Substrate surfaces are primed with an appropriate primer for the sealant and substrate combination — concrete, masonry, aluminium, glass and tile all require different primer systems.
Sealant application: Sealant is applied in a continuous bead, tooled to achieve positive contact against both joint faces and the desired surface profile.
Inspection and documentation: Completed joint sealing is inspected against specification requirements and photographically documented.
Applications in SEQ Buildings
Expansion joints in façades and roofs, control joints in concrete slabs and walls, perimeter joints in balcony tiling, window and door perimeter seals, pipe and conduit penetrations, drainage channel perimeters and waterproofing membrane termination flashings. Joint integrity is especially important on Gold Coast coastal buildings where wind-driven rain at elevation creates extreme pressure differentials across the building envelope.
Call [Phone Number — to be confirmed] to arrange a joint condition assessment. See also: Remedial Waterproofing | Balcony and Terrace Waterproofing | Concrete Leak Sealing
Frequently Asked Questions
Q: Can you re-seal joints without removing all the old sealant? No, not if a durable result is required. Applying fresh sealant over old sealant that has debonded, hardened or is contaminated does not produce an adequate bond. Full removal and reapplication is the only method that provides a warranted, compliant result.
Q: What is the difference between silicone and polyurethane sealant for joints? Silicone sealants offer excellent UV and temperature resistance and are suitable for glass, aluminium and some masonry substrates. Polyurethane sealants provide better adhesion to concrete and masonry surfaces, are paintable and generally perform better in high-movement applications. Selection depends on joint substrate, movement range and finish requirements.
Q: How often should building joints be inspected? Building envelope joints should be inspected as part of a scheduled maintenance programme, typically every 5 years and after significant weather events. Joint condition is often the first indicator of broader waterproofing vulnerability in a building.
Q: Do you carry out joint repairs on high-rise buildings? Yes. We use scaffolding, EWP hire and rope access systems as required to access joints at any height. All at-height work is carried out under site-specific SWMS and, where required, high-risk work licences.

Tile-over finishes. QBCC licensed applicators. URL Slug: /balcony-terrace-waterproofing Primary Keyword: balcony waterproofing Brisbane Secondary Keywords: balcony waterproofing Gold Coast, terrace waterproofing QLD, exposed balcony membrane Brisbane, AS 4654 waterproofing SEQ
Balcony and Terrace Waterproofing — Brisbane &amp; Gold Coast
Balcony waterproofing protects concrete slabs, structural steel and the spaces below from water penetration through exposed outdoor decks and terraces. Innovare Waterproofing installs and remediates membrane systems for balconies, terraces, roof decks and external walkways across Brisbane, the Gold Coast and South East Queensland — all specified and installed to AS 4654.2.
The Balcony Waterproofing Challenge
Exposed balconies are among the most demanding waterproofing environments in any building. The membrane must withstand:
UV radiation — in South East Queensland, UV intensity is among the highest in Australia. Without a protective topping, unprotected membranes degrade rapidly.
Thermal movement — concrete balcony slabs expand and contract with temperature. In a Brisbane summer, a dark concrete surface can cycle through 40°C in a single day. The membrane must be flexible enough to accommodate this movement without cracking.
Foot traffic — balconies used as outdoor living areas are subject to regular foot traffic, furniture loads and the occasional dropped item.
Ponding water — inadequate falls lead to ponding, which accelerates membrane degradation and tile delamination.
Wind-driven rain — at elevation, rain is driven horizontally as well as vertically, testing upstands, flashings and perimeter details.
Balcony Membrane Systems
Liquid-Applied Polyurethane Membranes Two-component polyurethane membranes applied by roller, brush or spray — providing seamless, fully-adhered waterproofing that conforms to irregular shapes and drains. Suitable for tile-over applications with appropriate primer and adhesive systems.
Sheet Membrane Systems Reinforced sheet membranes (modified bitumen or synthetic) offering high tensile strength and tear resistance — appropriate for large balcony areas and those subject to significant structural movement.
Polyurethane Deck Coatings For trafficable balconies without tile finishes — PMMA, polyurethane or polyurea-based wearing surfaces that combine waterproofing and abrasion resistance in a single system.
Falls and Drainage
Adequate falls are fundamental to balcony waterproofing longevity. AS 1428.1 and good waterproofing practice require a minimum 1:100 fall toward drainage outlets. We verify existing falls before applying new membranes and advise where screed overlay is required to achieve compliant fall gradients.
Remedial Balcony Waterproofing
Balcony membrane failure is among the most common remedial waterproofing scenarios in Brisbane and Gold Coast apartment buildings. Failed balconies manifest as:
Water staining and moisture damage to the soffit of the balcony below
Tile delamination and grout cracking
Rust staining at slab edges indicating rebar corrosion
Visible membrane cracking or delamination at perimeter flashings
Full membrane replacement — tile removal, existing membrane stripping, substrate preparation and new membrane installation — is the correct approach for failed balcony systems. Partial solutions typically fail within a short period.

Frequently Asked Questions
Q: Can balcony waterproofing be done without removing the tiles? Partial repairs (perimeter sealant replacement, drain resealing) can sometimes be carried out without full tile removal if the membrane substrate is otherwise sound. However, for a compliant, warranted membrane replacement, tile removal is required. We will advise honestly on whether a partial repair is feasible for your specific situation.
Q: What is the expected service life of a balcony membrane? A correctly installed, protected (tile-over) balcony membrane can provide 15–25 years of service. Exposed (unprotected) membranes have a shorter service life — typically 10–15 years — due to UV exposure. Regular inspection and timely maintenance extends service life significantly.
Q: My balcony tiles are cracking — is this a waterproofing problem? Not necessarily, but tile cracking can indicate an underlying waterproofing or substrate issue. Tile cracking can result from inadequate expansion joints, substrate movement, adhesive failure or a compromised membrane. We assess the cause before recommending a repair approach.
Q: Are you able to waterproof balconies in occupied apartment buildings? Yes. We work regularly in occupied strata buildings and coordinate access with building managers and body corporates to minimise disruption to residents.

Meta Title: Bathroom Waterproofing Brisbane &amp; Gold Coast | AS 3740 Compliant Meta Description: AS 3740 bathroom waterproofing for Brisbane and Gold Coast homes and apartments. Inspection certificates provided. QBCC licensed waterproofers. Call today. URL Slug: /bathroom-waterproofing Primary Keyword: bathroom waterproofing Brisbane Secondary Keywords: bathroom waterproofing Gold Coast, AS 3740 waterproofing QLD, wet area waterproofing Brisbane, shower waterproofing SEQ
Bathroom Waterproofing — Brisbane &amp; Gold Coast
Bathroom waterproofing is a regulated construction activity in Queensland. Innovare Waterproofing installs compliant wet-area waterproofing systems for bathrooms, ensuites, shower enclosures and laundries across Brisbane, the Gold Coast and South East Queensland — all to AS 3740, by QBCC-licensed applicators, with written inspection certificates.
Why Bathroom Waterproofing Is Critical
A failed bathroom membrane is one of the most costly and disruptive building defects a homeowner or apartment owner can face. Water penetrating a wet-area substrate migrates through structural slabs and walls, creating:
Significant mould contamination in wall cavities and ceiling voids
Structural timber rot in framed construction
Concrete and tile delamination
Damage to adjacent rooms, lower-level ceilings and common property elements in strata buildings
Potential public health issues from mould exposure
In many cases, the visible damage — a stained ceiling, a warped timber floor — has been accumulating for months or years before discovery. Correct waterproofing on installation is far less expensive than remediation.
Australian Standard AS 3740
AS 3740 — Waterproofing of Domestic Wet Areas — prescribes the minimum requirements for waterproofing in residential wet areas, including:
Application areas and dimensions — which surfaces must be waterproofed, and to what height
Membrane products — which membrane types are acceptable and what coverage rates apply
Substrate requirements — minimum substrate preparation and priming standards
Terminations and flashings — how membranes must be terminated at drains, penetrations, perimeter beams and wall junctions
Inspection — what must be inspected and documented before the membrane is covered
We apply every bathroom waterproofing installation to the current version of AS 3740 and provide written inspection certificates confirming compliance.
Our Bathroom Waterproofing Process
Strip and prepare — existing tiles, screed and failed membrane are removed. The substrate is checked for damage, repaired where necessary and prepared to specification (clean, sound, primed).
First coat application — liquid-applied membrane is applied at the specified coverage rate. Special attention is given to internal corners (which receive a reinforcing fabric strip), penetrations (which receive cut-in detailing) and the drain interface.
Curing — first coat is allowed to cure fully before the second coat is applied.
Second coat application — second coat is applied at specified coverage rate in a cross-direction to the first coat, providing uniform film thickness.
Inspection — completed membrane is inspected against AS 3740 requirements and photographically documented.
Certificate — written inspection certificate is issued for the client’s building records.
Protection — screed, tile bedding or other protection is applied before tiling commences.
Inspection Certificates for Building Certification
Building surveyors and private certifiers in Queensland routinely require evidence of AS 3740 compliant waterproofing as a condition of occupation certification. Our written inspection certificates satisfy this requirement and are prepared to a format suitable for submission.
Call [Phone Number — to be confirmed] to book a bathroom waterproofing installation or assessment. See also: Residential Waterproofing | Waterproofing Inspections | Remedial Waterproofing
Frequently Asked Questions
Q: Does a bathroom waterproofing inspection certificate expire? No. The inspection certificate documents compliance with the standard at the time of installation. It does not expire. However, the physical membrane system installed has a finite service life — a bathroom membrane that was installed 15 or more years ago may be approaching the end of its reliable service life regardless of what the original certificate said.
Q: What is the minimum waterproofing height in a shower? Under AS 3740, shower walls must be waterproofed to a minimum height of 1,800 mm above the shower floor, or full height if the shower enclosure is not fully enclosed. Floor areas and a 100 mm turn-up at wall junctions are also required. We apply membranes to the required dimensions and document them.
Q: Can you waterproof a bathroom in a strata apartment without accessing the apartment below? For new membrane installations in properly detailed bathrooms with membranes applied to the positive (top) face of the substrate, access to the apartment below is not required. For investigation of an active leak, access to the space below may be required to identify the water pathway.
Q: How soon after waterproofing can tiling commence? Curing time varies with product, temperature and humidity. As a general rule, a liquid-applied membrane is ready for tiling after a minimum of 24–48 hours under typical SEQ conditions. We will advise the specific cure time for the product we have applied.

Roof Membrane Systems — Brisbane &amp; Gold Coast
Innovare Waterproofing installs and remediates waterproofing membrane systems for flat and low-pitched roofs across Brisbane, the Gold Coast and South East Queensland. We apply torch-on modified bituminous membranes, liquid-applied polyurethane systems and reinforced sheet membranes to residential, commercial and industrial rooftops — all with written warranties and full substrate preparation documentation.
Flat and Low-Pitched Roof Waterproofing in SEQ
Flat and low-pitched roofs are common in both commercial construction and contemporary residential design across South East Queensland. They present a demanding waterproofing environment:
High UV intensity — Queensland’s solar intensity degrades unprotected membrane surfaces more rapidly than in southern states.
Thermal cycling — dark rooftop surfaces absorb heat, creating extreme thermal expansion and contraction cycles that fatigue membrane bonds and terminations.
Ponding water — inadequate fall produces standing water that accelerates UV degradation and forces water against terminations.
Storm intensity — South East Queensland experiences severe convective storms that can deliver 50–100 mm of rainfall in under an hour. Roof waterproofing and drainage must accommodate peak flow rates, not just average rainfall.
Roof Membrane Systems We Install
Torch-On Modified Bituminous Membrane SBS or APP-modified bituminous sheet membranes, applied by heat fusion (torch) to prepared concrete or screed substrates. A proven, durable system for large commercial rooftop areas. Typically finished with reflective mineral surfacing or an additional cap sheet.
Liquid-Applied Polyurethane Membrane Seamless, joint-free liquid-applied membranes applied by roller, brush or spray. Excellent for complex rooftop geometries with multiple penetrations, upstands and flashings. Available in a range of colours — light colours reduce solar heat gain.
Liquid-Applied PMMA (Polymethyl Methacrylate) Rapid-curing, high-performance liquid membranes suitable for projects with programme constraints — PMMA systems can be walked on within hours of application. Also suitable for rooftop terraces and trafficable roof decks.
Reinforced Sheet Membrane Systems TPO, PVC or EPDM sheet membranes for large commercial rooftop applications — offering long service life and factory-controlled material thickness.
Rooftop Drainage and Falls
We inspect drainage outlets, downpipes and roof falls as part of every roof membrane assessment. Blocked or inadequately sized drainage is a primary cause of premature membrane failure. Where falls are inadequate, we advise on screed overlay options to achieve minimum fall gradients before membrane installation.
Roof Membrane Remediation
Failed roof membranes manifest as internal ceiling leaks, visible membrane cracking and blistering, delaminated mineral surfacing, rusted penetrations and failed flashing details. We carry out full membrane replacement and targeted repair works depending on the extent of failure identified by investigation.
Call [Phone Number — to be confirmed] to arrange a roof membrane assessment or quotation. See also: Balcony and Terrace Waterproofing | Commercial Waterproofing | Remedial Waterproofing
Frequently Asked Questions
Q: How long does a torch-on roof membrane last? Quality SBS torch-on systems, correctly installed on a prepared substrate, typically provide 15–25 years of service on protected (ballasted or pavers) applications, and somewhat shorter on exposed applications subject to direct UV. Regular inspections and timely maintenance of termination details and flashings significantly extend service life.
Q: Can a liquid-applied membrane be applied over an existing torch-on membrane? In some circumstances, yes — if the existing membrane is firmly bonded, clean and structurally sound, a liquid-applied overlay may extend service life. However, for an ageing, delaminating or significantly cracked membrane, full replacement provides the most durable outcome. We assess existing conditions before recommending overlay versus replacement.
Q: Can you waterproof a roof with plant or solar panels on it? Yes, though the scope and sequence of work require coordination with the electrical and mechanical services involved. We have experience working around rooftop plant, drainage infrastructure and solar arrays. We will advise on temporary relocation requirements at quotation stage.
Q: Do you handle roof drainage as well as waterproofing? We assess drainage as part of every roof membrane scope and provide recommendations on drainage adequacy. We install new drainage outlets and sumps as part of waterproofing works. For major drainage infrastructure changes, we can coordinate with a licensed plumber.

Hydrostatic pressure specialists. QBCC licensed. URL Slug: /basement-waterproofing Primary Keyword: basement waterproofing Brisbane Secondary Keywords: basement waterproofing Gold Coast, below-ground tanking QLD, basement leak repair Brisbane, hydrostatic waterproofing SEQ
Basement Waterproofing — Brisbane &amp; Gold Coast
Basement waterproofing — also called below-ground tanking — controls water ingress into below-ground habitable and parking spaces through positive-side membranes, negative-side coatings and cavity drain systems. Innovare Waterproofing designs and installs below-ground waterproofing systems for residential and commercial basements across Brisbane, the Gold Coast and South East Queensland.
Waterproofing Challenges Below Ground in SEQ
Brisbane and the Gold Coast’s topography and groundwater conditions create significant below-ground waterproofing challenges. The river flats and coastal lowlands that contain much of the region’s residential and commercial development have high groundwater tables — particularly seasonally. Inner Brisbane’s hilly terrain creates significant retained-face hydrostatic pressure on basement walls.
Concrete is not inherently watertight. Without purposive waterproofing, below-ground concrete structures admit water through construction joints, shrinkage cracks and the concrete matrix itself. The consequences — rising damp, mould, structural corrosion and flooding — are serious and costly.
Approaches to Basement Waterproofing
Positive-Side (External) Tanking Applied to the external face of the structure before backfill, positive-side membranes provide the most robust below-ground waterproofing solution — the membrane resists hydrostatic pressure in compression. Systems include bituminous sheet membranes, liquid-applied polyurethane and bentonite clay board systems.
When positive-side access is no longer available (existing structures), negative-side and cavity drain approaches are required.
Negative-Side (Internal) Waterproofing Applied to the internal face of an existing below-ground structure. Cementitious crystalline and slurry systems bond to the substrate and resist hydrostatic pressure by penetrating the concrete matrix. Negative-side systems must be applied to sound, clean substrate and must be mechanically fixed or chemically bonded to resist hydrostatic uplift.
Cavity Drain Systems Dimple-profile drainage membranes (cavity drain boards) are fixed to the internal face of below-ground walls, creating a controlled drainage channel that directs water to a sump and pump. The cavity drain system does not stop water entry but controls it, providing a dry interior finish. This approach is suitable where substrate conditions prevent effective membrane application or where the structure is subject to ongoing movement.
Integrated Systems Most practical basement waterproofing designs combine elements of the above approaches — for example, cementitious crystalline coating on walls combined with a cavity drain system and sump pump for high-groundwater conditions.
Basement Remediation — Existing Structures
For existing basements with water ingress, our investigation process identifies entry points, hydrostatic pressure conditions and substrate condition before specifying a remedial approach. Active leaks are addressed first with crack injection and cementitious plugging, followed by the appropriate membrane or drainage system.

Frequently Asked Questions
Q: What is the best waterproofing system for a Brisbane basement? The best system depends on site groundwater conditions, construction type and whether positive-side access is available. For new construction with access, a positive-side sheet or liquid-applied membrane is generally preferred. For existing structures with active ingress, cementitious crystalline combined with a cavity drain and sump is often the most practical solution. We provide a specific recommendation based on site investigation.
Q: Can basement waterproofing be applied from the inside? Yes. Negative-side cementitious crystalline systems are specifically designed for internal application and resist hydrostatic water pressure. Cavity drain systems are also entirely internal. These approaches are the standard for remedial basement waterproofing where external access is not available.
Q: What happens to a basement waterproofing system in a flood? Basement waterproofing systems are not typically designed to resist full flood inundation pressures — the weight of floodwater above and around the structure may exceed the system’s capacity. However, high-performance positive-side tanking combined with sump systems can provide significant flood resistance. We advise on realistic performance expectations for your site conditions.
Q: Does basement waterproofing require council approval? In most cases, waterproofing to an existing basement as a remedial measure does not require separate building approval. However, if basement works are part of a larger structural modification or new development, they will be included in the overall approval. We advise on approval requirements as part of the scoping process.

Car Park Waterproofing — Brisbane &amp; Gold Coast
Car park waterproofing protects structural concrete from water, chloride and traffic-load damage in above and below-ground parking structures. Innovare Waterproofing installs traffic-bearing membrane systems, expansion joint repairs and protective coatings for multi-level car parks across Brisbane, the Gold Coast and South East Queensland.
Car Park Waterproofing Requirements
Car park decks present a unique combination of waterproofing and protective coating requirements:
Traffic loading — membranes must withstand vehicular loading without delaminating, tearing or losing adhesion, while remaining flexible enough to accommodate structural movement.
Chemical exposure — tyre oils, fuel spills, brake dust and cleaning chemicals are aggressive toward standard membranes. System selection must account for chemical resistance.
Chloride ingress — vehicle-borne road salt and coastal airborne chlorides penetrate failing or absent coatings, initiating rebar corrosion and the visible spalling and rust staining cycle.
Movement joint complexity — multi-storey car parks have extensive expansion joint networks that must accommodate significant thermal and structural movement while remaining watertight.
Drainage — adequate positive falls and unblocked drainage outlets are critical to preventing ponding, which accelerates membrane degradation.
Traffic-Bearing Membrane Systems
Polyurethane Traffic Deck Coatings Two-component polyurethane systems applied in multiple coats — primer, base coat, reinforcement layer and wearing surface. The wearing surface provides abrasion resistance and slip resistance, while the membrane layers provide waterproofing and flexibility.
PMMA (Polymethyl Methacrylate) Systems Rapid-curing PMMA membranes that can be returned to traffic within hours of application — critical for staged works in operating car parks. High UV stability and chemical resistance.
Methyl Methacrylate (MMA) Systems Similar to PMMA, MMA systems are used for both horizontal and vertical applications in car parks, providing seamless waterproofing with good abrasion and chemical resistance.
Expansion Joint and Movement Joint Repair
Car park expansion joints are high-failure areas. We carry out joint survey, documentation and complete joint repair and replacement using hybrid systems — including nosing repair, joint sealant replacement and proprietary joint cover systems designed for traffic-bearing applications.
Below-Ground Car Park Waterproofing
For below-grade car parks experiencing water ingress through walls, columns and floor slabs, we carry out crack injection, crystalline treatment and cavity drain installation as described in our Basement Waterproofing and Concrete Leak Sealing pages.
Working in Operating Car Parks
We regularly carry out car park waterproofing works in stages, maintaining partial car park operation throughout. Works are scheduled at low-traffic periods where possible and cordoned to meet Work Health and Safety requirements. We provide traffic management plans and SWMS as required.
Call [Phone Number — to be confirmed] to arrange a car park waterproofing assessment or quotation. See also: Basement Waterproofing | Concrete Protective Coatings | Joint Repair
Frequently Asked Questions
Q: How long does it take to waterproof a car park? This depends on the area, system selected and whether the car park remains in operation during works. A typical two-level car park resurfacing project takes two to four weeks when staged to maintain partial operation. PMMA and MMA systems reduce out-of-service time per bay to hours.
Q: My car park has rust staining and spalling — is waterproofing alone enough? No. Where reinforcement corrosion has already produced spalling, the structural concrete must be repaired and the rebar treated before a new membrane is applied. We carry out concrete repair and corrosion treatment works as part of an integrated car park rehabilitation scope. See Concrete Protective Coatings.
Q: Do you provide condition reports for car park waterproofing for body corporate purposes? Yes. We provide written condition assessments with photographic documentation of car park waterproofing condition, suitable for body corporate planning and tendering purposes.
Q: What is the expected service life of a car park membrane? A quality traffic-bearing membrane system correctly installed in a car park structure typically provides 10–20 years of service, subject to traffic volume, chemical exposure and maintenance standards. Regular inspection and prompt repair of isolated damage extends system life significantly.

URL Slug: /rising-damp-treatment Primary Keyword: rising damp treatment Brisbane Secondary Keywords: chemical injection DPC Brisbane, rising damp Gold Coast, damp proof course injection QLD, sub-floor ventilation Brisbane
Rising Damp Treatment — Brisbane &amp; Gold Coast
Rising damp occurs when ground moisture travels upward through porous masonry or concrete walls by capillary action, causing visible damp patches, salt efflorescence, paint failure and mould growth at the base of walls. Innovare Waterproofing diagnoses and treats rising damp in residential and commercial buildings across Brisbane, the Gold Coast and South East Queensland.
Understanding Rising Damp in SEQ
Rising damp is particularly prevalent in older building stock — homes and commercial buildings constructed before the widespread adoption of physical damp-proof courses (DPCs). Inner Brisbane suburbs such as Paddington, Red Hill, Hendra, New Farm, Woolloongabba and Auchenflower contain significant concentrations of homes and commercial buildings that are candidates for rising damp treatment.
A genuine physical DPC — a horizontal barrier of impermeable material (slate, lead, bitumen-impregnated felt, or modern plastics) installed within the wall during construction — prevents capillary rise. When the original DPC has failed, deteriorated or is absent, moisture rises freely.
Diagnosis: Is It Rising Damp?
Rising damp is frequently confused with other moisture problems — condensation, horizontal penetrating damp and plumbing leaks can all produce similar-looking symptoms. Misdiagnosis leads to ineffective and costly treatment.
We carry out moisture testing using calibrated electrical resistance meters and, where appropriate, calcium chloride or gravimetric analysis to distinguish rising damp from condensation. We also check for contributing factors: blocked sub-floor ventilation, raised ground levels against walls and leaking gutters or downpipes.
Treatment Methods
Chemical Injection Damp Proof Course A line of injection holes is drilled at mortar-course level around the affected walls. Silicone-based water-repellent cream or liquid is injected into the holes, which diffuses through the masonry and polymerises to create a hydrophobic band — effectively a chemical DPC. The holes are plugged with matching mortar on completion.
This method is appropriate for solid brick walls and some concrete masonry units. It is not effective in all wall construction types — we will advise on suitability following investigation.
Sub-Floor Ventilation Many Brisbane homes with timber floor frames on stumped foundations suffer from inadequate sub-floor ventilation. Poor ventilation leads to moisture accumulation, condensation on the underside of flooring and rising damp in adjacent masonry walls. We install additional ventilation products, sub-floor ducted fans and vapour barriers to improve sub-floor conditions.
Electro-Osmotic Systems In situations where chemical injection is not appropriate, electro-osmotic pulse systems can reverse the capillary pressure gradient driving moisture rise. These systems are typically used in heritage buildings where drilling into fabric is constrained.
Drainage and Ground Level Management In some cases, the most cost-effective rising damp solution is reducing external ground levels, improving perimeter drainage and redirecting surface water away from the building. We identify drainage contribution as part of every rising damp investigation.

Frequently Asked Questions
Q: How do I know if I have rising damp or just condensation? Rising damp typically presents as a horizontal tide mark at the base of walls, with salt efflorescence (white crystalline deposits) and paint bubbling at a fairly consistent height — usually below 1.0 m. Condensation tends to appear at cold spots higher on walls, particularly on north-facing walls or in poorly ventilated rooms. We use moisture meters and testing to confirm the diagnosis.
Q: How long does chemical injection DPC last? Quality silicone-based chemical DPC products have demonstrated service lives of 20–25 years or more in controlled conditions. Long-term performance is dependent on correct application and appropriate plaster renovation after treatment.
Q: After chemical injection, how long before I can replaster the walls? Walls need to dry out after treatment — moisture must evaporate before replastering. This process typically takes a minimum of six months to a year in SEQ conditions. We recommend using a salt-resistant, moisture-tolerant renovating plaster rather than standard cement render.
Q: Do you treat rising damp in heritage buildings? Yes, with appropriate care. Heritage-listed buildings often have additional constraints on drilling and treatment methods, and the selection of breathable render systems after treatment is particularly important. We work with heritage building owners and can liaise with heritage consultants as required.

Waterproofing Inspections — Brisbane &amp; Gold Coast
Innovare Waterproofing provides pre-purchase waterproofing inspections, building defect reports, AS 3740 compliance audits and expert assessments for residential and commercial properties across Brisbane, the Gold Coast and South East Queensland. Our inspections identify existing failures, assess system condition and provide actionable recommendations.
When Is a Waterproofing Inspection Needed?
Pre-Purchase Inspections Before buying a house, apartment or commercial property, understanding the condition of the waterproofing systems protects you from unexpected post-settlement costs. Standard building inspections often identify surface symptoms without investigating waterproofing system condition in detail. Our waterproofing-specific inspections provide a deeper assessment.
Strata and Body Corporate Condition Assessments Body corporates managing ageing buildings benefit from building-wide waterproofing condition assessments — identifying systems approaching end of service life, active defects and maintenance priorities. This information informs maintenance budgets and sinking fund plans.
Pre-Construction Inspections Inspection of waterproofing during construction — at substrate preparation, first coat and completed membrane stages — as required by AS 3740 and standard building surveyor requirements. We provide written inspection certificates for private certifiers.
Defect Investigations When water ingress has been identified in a property, we carry out a systematic investigation to identify the source, extent and cause of the defect — providing written reports suitable for insurance claims, BCCM dispute resolution or litigation support.
Compliance Audits For existing waterproofing installations where compliance records are absent — common in older buildings and after change of ownership — we carry out AS 3740 and AS 4654.2 compliance assessments and provide written findings.
Expert Witness Reports We provide expert waterproofing reports for use in legal proceedings, arbitration, BCCM adjudications and QCAT applications. Our reports are prepared with appropriate objectivity and comply with applicable expert witness requirements.
What Our Inspections Cover
A comprehensive waterproofing inspection typically includes:
Visual inspection of all accessible wet areas, balconies, roofs and external surfaces
Moisture meter testing of walls, floors and ceilings in and around suspect areas
Flood/hose testing of shower enclosures and balconies
Inspection of drain outlets, flashings and perimeter details
Assessment of joint and sealant condition
Photographic documentation of all findings
Written report with findings, cause assessment and remediation recommendations
Inspection Reports
Our written inspection reports are clear, factual and actionable. They include:
Executive summary of findings
Photographic evidence for each finding

Frequently Asked Questions
Q: Is your inspection independent, or will you always recommend your own repair services? Our inspections are carried out objectively. We provide an honest assessment of condition and recommendations. Where remedial works are required, we can provide a quotation — but you are under no obligation to use us for the repair work. Many clients engage us purely for the inspection report and obtain competitive quotes from multiple contractors.
Q: What does a pre-purchase waterproofing inspection cost? Inspection fees vary with property size, type and accessibility. We provide a fixed-fee quotation for every inspection before it is carried out. Contact us on [Phone Number — to be confirmed] for an indicative fee.
Q: Can you provide expert waterproofing reports for QCAT proceedings? Yes. We have prepared waterproofing expert reports for QCAT applications, BCCM adjudications and associated proceedings. These reports are prepared with the objectivity required of expert witnesses and comply with applicable court and tribunal practice directions.
Q: Do you issue AS 3740 certificates for third-party inspection of works installed by another contractor? We can inspect waterproofing works installed by another contractor and provide a written assessment of whether the installation appears compliant with AS 3740. However, we will not issue a compliance certificate for works we did not install without reservations, as we cannot warrant the full application process for works we did not observe throughout.

Projects Gallery — Waterproofing Work Across Brisbane and the Gold Coast
Innovare Waterproofing documents every project from investigation through to installation completion. Our gallery showcases the quality, scope and range of our waterproofing work — before, during and after. From single-bathroom membrane replacements in suburban Brisbane to multi-storey podium deck remediation on the Gold Coast, the gallery reflects the breadth of our team’s experience.
How We Document Our Work
Every project is photographically documented at three stages:
Investigation and preparation — existing conditions, defect close-ups, substrate condition after membrane removal.
During application — membrane application stages, detailing at penetrations and junctions, inspection photographs.
Completion — finished membrane system before topping application, and completed installation in finished condition.
This documentation record serves multiple purposes — it is our quality record, it provides evidence for warranty purposes, and it gives future owners and facility managers a permanent record of what is installed beneath the surface finish.

Waterproofing Insights — Brisbane &amp; Gold Coast
Welcome to the Innovare Waterproofing blog — practical, expert-written waterproofing advice for homeowners, property managers, builders and body corporate committees across Brisbane, the Gold Coast and South East Queensland.
Our articles are written by the people who install and repair waterproofing systems every day. You will find straight-talking guidance on diagnosing leaks, understanding Australian Standards, evaluating membrane systems and managing waterproofing as part of property maintenance planning.
Featured Articles
1. How to Diagnose a Roof Leak in a Queensland Home — And Why It’s Usually Not Where You Think Water is a traveller. A wet ceiling patch is rarely directly below the point of roof entry — water runs along structural members, accumulates in voids and emerges metres from the actual breach. This article walks through the systematic approach to roof leak diagnosis: what to check first, how to narrow the search area and when to call a specialist.
2. AS 3740 Explained: What Queensland Homeowners Need to Know About Bathroom Waterproofing Australian Standard AS 3740 governs the waterproofing of domestic wet areas in Queensland — but most homeowners have never heard of it. This article explains what the Standard requires, why it matters for renovations and resale, and what a compliant waterproofing installation actually looks like.
3. Why Brisbane Balconies Fail — And What to Do When Yours Does Brisbane’s subtropical climate is particularly hard on balcony membranes. UV intensity, thermal cycling and intense summer storms combine to degrade even well-installed systems within 10–15 years. This article examines the signs of balcony membrane failure, the risks of ignoring them and what a full remedial scope involves.
4. Rising Damp in Older Brisbane Homes — Separating Myth from Reality Rising damp is one of the most misdiagnosed moisture problems in residential property. In Brisbane’s inner suburbs, where pre-1960s masonry construction is common, damp at the base of walls is frequently attributed to rising damp when condensation, penetrating damp or plumbing leaks are actually responsible. This article explains how to tell the difference.
5. Body Corporate Waterproofing Budgets: Planning for Your Building’s Major Remediation Cycle Multi-storey residential buildings in Brisbane and the Gold Coast are entering their first and second major remediation cycles. Balcony membranes, basement waterproofing and roof systems all have finite service lives — and body corporate sinking fund contributions need to reflect the cost of eventual renewal. This article provides a framework for body corporate waterproofing budget planning.
6. Crack Injection vs Surface Patching: When Is Each Appropriate for Concrete Cracks? Concrete cracks are common, but not all cracks are the same — and not all treatments are appropriate for every crack type. Surface patching is quick and cheap but rarely durable for cracks subject to ongoing movement or water pressure. This article explains when crack injection is the correct approach and when surface patching may be adequate.

Frequently Asked Questions — Waterproofing Brisbane &amp; Gold Coast
Answers to the most common questions we receive about waterproofing systems, standards, costs, warranties and processes. If your question is not answered here, call us on [Phone Number — to be confirmed] — we are happy to help.
Q: What is AS 3740 and does it apply to my bathroom?
AS 3740 — Waterproofing of Domestic Wet Areas — is the Australian Standard that prescribes minimum requirements for waterproofing in residential bathrooms, ensuites, laundries, toilets and other wet areas. It applies to all domestic residential wet-area construction in Australia, including new builds and renovations.
Under the National Construction Code (NCC), compliance with AS 3740 is required for new residential construction and renovation work that involves wet areas. In Queensland, waterproofing of wet areas is a regulated activity — it must be carried out by a QBCC-licensed waterproofer, and a written inspection certificate must be provided.
If you are renovating a bathroom, replacing tiles or replacing wet-area finishes, the waterproofing membrane must be inspected and certified before tiling proceeds. Tiling over an existing membrane without inspection and certification is not compliant.
Q: What warranty should I expect on waterproofing work?
Written warranties on waterproofing work typically reflect the system type, substrate condition and application scope. As a general guide:
New wet-area bathroom membranes (AS 3740): most quality installers provide warranties of five to ten years on workmanship.
Liquid-applied external membrane systems (balconies, roofs): workmanship warranties of five to ten years are common; manufacturer system warranties of up to twenty years may be available on qualifying projects.
Traffic-bearing car park systems: workmanship warranties of three to seven years are typical.
Crack injection and remedial leak sealing: workmanship warranties of two to five years on the specific treatment.
Always ask for a written warranty before works commence — verbal warranties are difficult to enforce. At Innovare Waterproofing, we provide written warranties on every installation.
Q: How much does waterproofing cost?
Waterproofing costs vary significantly depending on the application type, substrate condition, access requirements and system specification. It is not possible to provide reliable ballpark figures without a site inspection. As a general orientation:
Bathroom membrane (new installation): cost is typically modest and reflects the area waterproofed, system selected and substrate preparation required.
Balcony remedial waterproofing (tile removal and membrane replacement): preparation costs (tile removal and disposal, substrate repair) often exceed the membrane application cost itself.
Commercial and large-scale projects: quoted on a project-specific basis after investigation.
We provide transparent, itemised written quotations following site inspection. We do not quote without inspecting.
Q: How do I know if my waterproofing has failed?
Common indicators of waterproofing failure include:
Water staining, mould or moisture on walls, ceilings or floors adjacent to or below wet areas
Tiles or flooring that are hollow-sounding, delaminating or have visible grout cracking
Musty odours in rooms adjacent to bathrooms, balconies or roofs
Rust staining or concrete spalling on balcony soffits or edges
Visible damp patches at the base of external walls (potential rising damp)
Ponding water on balconies or rooftops
If you observe any of these signs, call us for an assessment — [Phone Number — to be confirmed].
Q: What causes waterproofing to fail prematurely?
The most common causes of premature waterproofing failure are:
Incorrect membrane selection — the wrong membrane type for the application.
Inadequate substrate preparation — applying membrane to dusty, damp, weakly bonded or unsound substrates.
Insufficient membrane thickness — applying at below-specification coverage rates to save material cost.
Poor detailing — inadequate treatment of internal corners, penetrations, perimeter flashings and drain interfaces.
Missing or inadequate reinforcement — corners and stress points require fabric reinforcement that is omitted in poorly executed work.
Applying over movement — applying a rigid membrane type across active structural movement without accommodating the movement.
Climatic exposure without UV protection — exposing a non-UV-stable membrane to Queensland UV without a protective coating or tile overlay.
Q: Can I waterproof my bathroom myself?
In Queensland, waterproofing of wet areas is a regulated construction activity under the QBCC Act. It must be carried out by a licensed waterproofer. Unlicensed waterproofing work cannot be certified, may invalidate building insurance and creates liability issues at resale. DIY waterproofing is not legally permissible for wet areas in Queensland residential properties.
Q: What is the difference between a waterproofing membrane and a tile sealer?
A waterproofing membrane is a purpose-designed barrier — either liquid-applied or sheet form — applied beneath tiles to the structural substrate. It prevents water from penetrating the substrate. A tile sealer is applied to the tile and grout surface to reduce staining and surface moisture absorption. A tile sealer does not waterproof the substrate beneath the tiles. These are entirely different products with entirely different functions. Many people believe their tiled bathroom is waterproof because the tiles are sealed — this is not the case. The waterproofing membrane beneath the tiles is what performs the waterproofing function.
Q: How long does it take for a waterproofing membrane to cure before tiling?
Cure times vary with product, temperature and humidity. Liquid-applied polyurethane and acrylic membranes under typical SEQ conditions (20–30°C, moderate humidity) are generally ready for tiling in 24–48 hours after the final coat. In cooler or high-humidity conditions, curing may take longer. We advise specific cure times for the product we have applied. Tiling before the membrane has fully cured can cause adhesion failure.
Q: Do you offer a maintenance programme for waterproofing systems?
Yes. For commercial, strata and body corporate clients with significant waterproofing assets, we can arrange periodic inspection and maintenance programmes — identifying early-stage deterioration in joints, flashings and membrane surfaces before failures develop. Proactive maintenance significantly extends system service life and reduces lifecycle costs. Contact us on [Phone Number — to be confirmed] to discuss a maintenance programme for your building.
Q: Are your waterproofing systems suitable for use in pools and water-retaining structures?
Yes. We apply waterproofing systems to pools, spas, water features, tanks and water-retaining structures using products specifically rated for water-contact and, where required, potable water contact applications. Not all waterproofing membranes are suitable for permanent water immersion — system selection for these applications requires specific product knowledge.
Q: What should I do if I discover a water leak after a waterproofing contractor has finished work?
First, document the leak — photographs, date and description of what you are observing. Then contact the waterproofing contractor who carried out the work, in writing, requesting they inspect and address the defect under their warranty obligations. If you do not have a written warranty or the contractor is unresponsive, contact the QBCC — they have a dispute resolution process for waterproofing defects in Queensland. If you would like an independent assessment of the defect to support a warranty or QBCC claim, Innovare Waterproofing can provide a written inspection report. Call [Phone Number — to be confirmed].
