Casula NSW 2170
Need a local waterproofer in Casula? AB Sydney Waterproofing is based just down the road in Liverpool, providing licensed waterproofing in Casula for houses, townhouses and units. We repair leaking showers, balconies, basements and pools with quality membranes – free inspection, written 7-year warranty.
Casula sits on the western bank of the Georges River, home to the Casula Powerhouse Arts Centre and the Crossroads shopping area. Its streets combine brick family homes from the 1970s to the 1990s with newer townhouse and villa developments, plus some homes on sloping blocks running down towards the river.
Older homes need original bathrooms and laundries brought up to standard, townhouse complexes need balconies and courtyards maintained, and sloping blocks need retaining walls that keep water out. Being so close, we can usually inspect quickly and fit jobs around you.
All our waterproofing services are available in Casula. Bathrooms, balconies, basements and pools get our closest attention – the areas Casula homes and townhouses rely on most.
Homes & villas
Leaking showers are the most common job we do in Casula, in original bathrooms and in townhouse en-suites. We repair failed membranes – often with tile injection – and waterproof new and renovated bathrooms to AS 3740.
Townhouses
Townhouse and villa complexes in Casula have balconies and courtyards above garages and living areas. When the membrane fails, water shows up as stains and drummy tiles. We re-waterproof them and work with strata where needed.
Sloping blocks
Homes on the slopes towards the Georges River often have garages and lower rooms built into the hillside. We waterproof retaining and below-ground walls so water stays out of garages, storerooms and living spaces.
Backyard pools
Many established Casula homes have backyard pools now old enough to start losing water. We repair cracks and joints and re-waterproof pool shells, and waterproof new pools before tiling.
Remedial roof membranes for homes, apartments and commercial buildings, built to handle UV, heat and heavy downpours.
We line and seal box gutters, sumps and outlets so heavy storms drain away instead of overflowing into the building.
Lift pits and shafts sealed against groundwater to protect lift equipment and stop corrosion in apartment and commercial buildings.
Laundries leak quietly behind machines and tubs. We waterproof the floor and walls properly so the problem doesn't come back.
Concrete and screed floors waterproofed for wet areas, ground floors and commercial spaces where water must stay out of the slab.
Epoxy resin injected under existing tiles seals a leaking shower without demolition – a faster, lower-cost fix when the tiles are still sound.
Garden beds built against walls and over slabs are a common hidden leak. We waterproof and drain them properly.
External brick walls, parapets and chimneys treated against damp and salt so moisture stops reaching the inside of the building.
Not sure where the water is coming from? We trace leaks through slabs, walls, showers and balconies before any work is quoted.
Every Casula job is done under Waterproofing Licence 36763C, so the work is recognised by insurers, certifiers and strata committees.
Our waterproofing comes with a 7-year written warranty – long after the tiles go down, we still stand behind the work.
Water rarely shows up where it gets in. A free inspection traces the leak to its source before we quote, so you pay to fix it once.
Wet areas are waterproofed to AS 3740 and outdoor areas to AS 4654, and you receive a compliance certificate when we finish.
We work for homeowners, landlords, builders, strata managers and businesses across Casula and nearby suburbs.
A free written quote that explains what’s wrong, the system we’ll use and the price – no surprises when the job is done.
These are the warning signs we see most in Casula homes and townhouses. We’re close by, so getting an inspection is easy.
