For Builders & Developers

Waterproofing for luxury builds and developments in Byron Bay and the Northern Rivers.

A specialist waterproofing subcontractor for high-end residential builds and boutique developments — the kind where the membrane is behind stone, the balcony is over a living room, and the pool is on a podium. Sequenced into your program, documented at every stage, and done right the first time.

We don't take on volume-builder work. The sequencing, the margins, and the quality expectations don't suit a specialist operation, and we'd rather do fewer jobs properly than more jobs to a price.

What we do take on is high-end residential and boutique developments — new builds and major renovations in Byron Bay, the Byron hinterland, and across the Northern Rivers where the specification calls for premium membrane systems, correct substrate preparation, and detailing that survives stone, tiling, and a lifetime of wet-area use.

The membrane is the stage you never see again. It's also the most expensive to redo — tiles off, stone off, screed up, residents out. So we do it once: substrate prepared to a standard the membrane can bond to, the right system for the substrate and the tile, full coverage to the required height, and every junction, drain and penetration detailed.

Podium and rooftop wet areas — membrane applied to the slab and upturns before the stone cap and finishes go on. The penetrations are sealed and detailed, not left for the tiler to find.

Build types we cover.

Beachfront & coastal homes

Direct-to-weather exposure, salt air, and high wind-driven rain. Membrane systems selected for UV and hydrostatic head, with detailing at sliding tracks, deck junctions and planter upturns.

Hinterland & acreage estates

Sloping sites, retaining structures, and basement/retaining-wall waterproofing where excavation access is limited. Negative-side options where the external face can't be reached.

Boutique multi-residential developments

Townhouse and low-rise apartment developments where the specification calls for a specialist subcontractor. Podiums, shared wet areas, balconies over habitable space, and basement plant rooms.

Podium pools & water features

Rooftop and podium pools, spas and reflection pools under constant hydrostatic head and UV. Membrane selection, substrate preparation, and detailing at drains, overflows and the pool shell.

Rooftop terraces & balconies

Pedestrian-grade waterproofing for terraces and balconies above habitable space — correct fall, drainage, junction detailing, and membrane selection for foot traffic and UV.

Basements & retaining structures

Basement walls, lift pits, and retaining walls — positive-side where accessible, negative-side injection and waterproofing where external access isn't possible.

How we work with your program.

Waterproofing is a hold-point stage, not a fill-in trade. We sequence it into the build, hold the substrate to a bondable standard, and hand over documentation so the next trade starts on a known surface. AS 3740 for domestic wet areas, AS 4654 for external above-ground membranes — installed to the standard, not to a price.

01 · Substrate hold

We inspect the substrate before we membrane. If it isn't dry, sound and clean, we flag it and hold until it is — no coating over a surface that won't bond.

02 · Membrane specification

The system is selected for the substrate, the tile, the exposure and the movement. Sheet, liquid, or hybrid — specified on the specifics of the wet area, not a default.

03 · Staging & hold-points

Wet areas staged in the right order, with key stages held and signed off — primer, coats, junction reinforcement — so the builder and the certifier have a record before the finish goes on.

04 · Documentation handover

Substrate condition, primer, membrane system, coats and coverage recorded and handed over. A defensible record of what's behind the tiles.
