Bathroom & Internal Wet Areas
High-performance, seamless water protection for new residential layouts and premium bathroom renovations.
What it is: The application of premium, Class III high-extensibility liquid membranes to critical wet zones before tiling. Unlike standard applicators, we manage the entire substrate preparation - including engineered sand-and-cement screeding to guarantee perfect structural falls (slopes) to the drainage outlets.
This process seals shower recesses, entire floor areas, floor-to-wall junctions, and plumbing penetrations to prevent internal moisture from breaching the structural framework.
Best for: Residential bathroom extensions, complete bathroom layout renovations, new-build ensuites, laundries, and secondary powder rooms.
Compliance & Handover: Every application is fully compliant with Australian Standard AS 3740. We supply a formal Certificate of Compliance, giving builders, owners, and councils absolute assurance that the wet areas are permanently sealed and perfectly sloped.
Rooftops, Podiums & Balconies
Heavy-duty, weather-resilient membrane systems engineered to withstand thermal movement and harsh climate exposure.
What it is: High-tech external waterproofing systems tailored for exposed concrete structural slabs. We utilize a combination UV-stable polyurethane liquid membrane systems. These systems handle intense sun exposure, extreme rainwater volumes, and the natural expansion and contraction of structural concrete.
Best for: Modern flat-roof residential architectures, apartment podium slabs, elevated balconies, open courtyards, and external box gutters.
Compliance & Handover: Installed strictly in accordance with Australian Standard AS 4654. We manage the entire process - including establishing correct structural falls and surface preparation, - backed by a comprehensive manufacturer and applicator warranty.
Retaining Walls & Planter Boxes
Robust, root-resistant external tanking barriers engineered to combat continuous soil moisture and heavy hydrostatic pressure.
What it is: A complete below-ground and landscape containment system. We install high-performance systems formulated with active root inhibitors to prevent vegetation from piercing the barrier.
Best for: New masonry or concrete retaining walls built against earth banks, structural basement walls, and architectural landscape planter boxes or garden beds.
Compliance & Handover: This service creates an unbreachable shield that prevents damp earth from bleeding through porous brick or concrete blocks. It keeps your architectural structures structurally sound, stain-free, and protected against long-term water pressure.
