Blacktown & Wyong — Secondary Dwelling Wet Areas
Complete washroom and laundry waterproofing for newly constructed secondary dwellings (granny flats), ensuring AS 3740 certification.
High-efficiency wet area waterproofing for contemporary secondary dwellings (granny flats) in Western Sydney and the Central Coast, certified under AS 3740:2021.
Precision Laser-Level Verification
Secondary dwellings often feature compact floor plans where the laundry door leads directly to an external perimeter pathway. To prevent moisture tracking outside or under timber floors, door threshold angles were calibrated using laser alignment.

- Double-recessed shower niches fully waterproofed with reinforced corner bandaging.
- Threshold waterstop angles bedded in polyurethane adhesive and mechanically fastened to concrete slab.
- Puddle flanges recessed and dressed to guarantee zero water pooling under floor tiles.
