Home Services Commercial Waterproofing

Commercial waterproofing, delivered to programme.

We work directly with builders, developers, body corporates and facility managers on shopping centres, multi-storey apartments, podiums, car parks, roofs and industrial facilities — with the documentation, programming discipline and insurances commercial projects demand.

The commercial capability of a builder, the focus of a specialist

Commercial waterproofing operates at a different scale and under different pressures to residential work. Programmes are tight and sequenced against other trades, defects carry significant liability, and the documentation requirements — ITPs, compliance statements, warranty schedules — are non-negotiable.

As a specialist division of the Innovare Group, we bring the commercial accountability of a licensed builder together with the technical depth of a dedicated waterproofing trade contractor. We understand construction programmes, we prepare the documentation your certifier and superintendent require, and we hold the insurances commercial projects demand.

We work both as a nominated subcontractor to principal builders on new construction, and directly for body corporates and facility managers on remediation of existing assets — from podium decks and car parks to plant rooms and roofs.
