Bathroom Waterproofing
The full internal wet area: floor, shower, hob, bath surround, vanity splash zone and every penetration. We apply liquid-applied membrane systems selected for your substrate — fibre cement sheet, compressed sheet, screed or concrete slab — and detail the junctions with reinforcing fabric before the second coat goes on.
What's included
- Substrate moisture and adhesion check before priming
- Angle fillets or bond breaker tape to all wall/floor junctions
- Sealing to 150mm minimum outside the shower area, higher where designed
- Puddle flange, waste and tap penetration detailing
- Two coats at specified wet film thickness, cure time respected
- Photo record and AS 3740 compliance certificate on completion
