Liquid membrane and sheet membrane waterproofing for wet areas, balconies, and below-grade commercial applications in Perth.
Commercial waterproofing failure discovered after wall tiling and fitout completion is one of the most costly defect scenarios on any commercial project in Perth. Our team specifies and installs liquid membrane and sheet membrane waterproofing systems, selecting the correct system type, thickness, and detailing approach for each specific application. All installations comply with AS 3740 wet area waterproofing requirements and relevant NCC provisions, with particular attention to terminations, penetrations, and junctions — the areas where most waterproofing failures originate. We work with builders and principal contractors on new construction and refurbishment projects across Perth, and every installation is documented with a compliance certificate that forms part of the building handover package. Waterproofing is a system that has to be designed, installed, and documented correctly — our technical reporting service ensures the documentation is in order from day one.
