Revesby NSW 2212
Searching for experienced waterproofers in Revesby? We specialise in waterproofing services in Revesby for homeowners, landlords, builders and strata managers. From bathroom leaks to pool and basement repairs, our licensed team gets it right the first time – free inspection, written quote, 7-year warranty.
From family homes to townhouses and units, the properties we waterproof in Revesby and across the Canterbury-Bankstown area vary a lot. What doesn’t change is our approach: inspect carefully, find the cause, and use a membrane system that suits the surface, the exposure and how the space is used.
We waterproof internal wet areas to AS 3740 and external areas to AS 4654, prepare every surface properly before the membrane goes on, and finish with a compliance certificate where required. That’s how we can back our work with a written 7-year warranty.
Every waterproofing service is available in Revesby. Bathroom, Pool, Basement and Laundry waterproofing get our closest attention, because they’re the jobs Revesby property owners call us for most.
Bathrooms
Most bathroom leaks start at the same few weak points: cracked grout, a poorly sealed floor waste, or a membrane that stops short at the wall. We find exactly where water is escaping and fix it – with tile injection when the tiles are sound, or a new membrane when they’re not.
Backyard pools
If you’re topping up the pool far more than usual, water is probably escaping through cracks, joints or a failed membrane. We find the leak, repair the shell and re-waterproof pools in Revesby – and waterproof new concrete pools before tiling.
Basements
Basements, garages and retaining walls hold back wet soil every day. Without a working membrane and drainage, water pushes through walls, slabs and joints. We waterproof Dincel, block and retaining walls on new builds in Revesby and repair seepage in existing basements.
Laundry leaks
A laundry needs the same protection as a bathroom. We seal the floor, perimeter upturns and penetrations properly so water from machines, tubs and mopping can’t reach the structure.
Balconies, terraces and courtyards re-membraned at door sills, drains and balustrades so water stops reaching rooms and ceilings below.
Flat concrete roofs and roof decks re-membraned so they shed water instead of ponding and leaking into the floor below.
Box and eaves gutters re-membraned so storm water runs off the roof instead of spilling into walls and ceilings.
Lift pits waterproofed to stop seepage, standing water and corrosion that can damage lift equipment and trigger costly call-outs.
Remedial floor membranes for wet areas, ground-floor slabs and commercial floors, matched to the substrate so water can't move through.
Shower leaking but tiles still solid? Resin injected through the grout lines can seal it in a day, without a full renovation.
Planter boxes and podium gardens lined with root-resistant membranes and proper drainage so they don't leak into walls or car parks.
External brick walls, parapets and chimneys treated against damp and salt so moisture stops reaching the inside of the building.
Our inspection finds the real source of a leak first, so you only pay to fix what's actually failing.
All work is carried out under Waterproofing Licence 36763C. Ask to see it on site – a licensed contractor protects you, your insurer and your strata.

Stains and damp patches can be metres from the real leak. We track the water back to where it enters before recommending a fix.
Internal wet areas to AS 3740 and external membranes to AS 4654, with a compliance certificate for your records, sale or strata.
These are the early warning signs that waterproofing has failed. Catch them early and the repair is usually smaller.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
More loss than evaporation usually means a failed membrane or joint.
Groundwater is getting past below-ground walls or joints.
Water is passing through the wall instead of draining behind it.
Water is wicking out of a wet area into the timber next to it.
