Surface-applied waterproof coatings and masonry sealers — for the water that comes in through the wall, not up through the floor.
A lot of water ingress in Sydney buildings isn't coming from a failed membrane under the tiles. It's coming straight through porous brickwork, unsealed render, and hairline cracking in the façade, driven in by wind on the wet side of the building. Those surfaces can be sealed from the outside, by rope, without lifting a single tile.
What we apply
Paintable waterproof membranes — flexible liquid-applied coatings brushed, rolled or sprayed to external walls, parapets and balcony walls, crack-bridging and UV stable
Penetrating brick and masonry sealers — repellents that soak into face brick and render, stopping wind-driven rain without changing the appearance
Anti-carbonation coatings — protective systems over concrete that resist both water and CO₂ ingress
Spray application at height — full elevations coated from rope for even film build and no roller lap lines
We'll tell you if a coating won't fix it.
Send through what you're seeing inside and we'll come and find the entry path. If it's under-tile or wet-area work, we'll say so.
