Waterproofing

Sydney waterproofing specialists

Certified waterproofing protection for bathrooms, laundries, balconies, decks and other wet areas across Sydney, NSW.

Waterproofing is one of the most critical stages of any wet-area build or renovation. Proper membrane work protects the structure beneath the tiles and helps prevent leaks, rot, and mould.

Sydney waterproofing specialists
Coverage

Comprehensive wet-area protection

Every waterproofing job is treated as a precise system, using liquid-applied and sheet membranes tailored to the condition of the home.

Bathrooms & ensuites

Complete sealing of shower recesses, bathroom floors, wall junctions, and splash zones.

Laundries & wet areas

Protection for high-risk utility zones exposed to appliance leaks, overflow, and ongoing moisture.

Balconies & external decks

Heavy-duty, UV-resistant barriers designed to withstand the elements and prevent water ingress.

Screeding & substrate preparation

Correct floor falls and preparation to support efficient drainage and help prevent water pooling.

Flexible floors

An advanced dual-layer system for flexible substrates

On timber and fibre-cement floors, movement can crack standard tiling and compromise waterproofing. This multi-layer approach is designed to reduce that risk.

Step 1

Initial membrane

Two full coats of premium flexible membrane applied directly to the prepared subfloor.

Step 2

Reinforced screed

A traditional sand-and-cement bedding screed with galvanised wire mesh to help reduce shrinkage and cracking.

Step 3

Secondary membrane

An additional two coats of high-flexibility membrane applied over the cured screed for extra protection.

Four total coats across a mesh-reinforced screed

This creates a strong decoupled waterproofing barrier designed to stay protective even as a home naturally moves and flexes over time.
