Need expert waterproofing in Bankstown? AB Sydney Waterproofing is a licensed waterproofing company in Bankstown trusted by homeowners, strata managers and businesses. We repair leaking balconies, bathrooms, basements and roofs with quality membrane systems, offering a free inspection and a written 7-year warranty on every job.
Bankstown is one of south-west Sydney’s major centres. The CBD around Bankstown Central, the station and Paul Keating Park is filled with apartment towers and mixed-use buildings, with shops and offices along Chapel Road and North Terrace. Beyond the centre, streets of post-war brick and fibro homes have been joined by duplexes and townhouses.
Apartment towers bring stacked balconies, deep basement car parks and lift pits, while older homes need bathrooms and laundries brought up to modern standards. With more development on the way, we also waterproof new builds from basement to rooftop.
Every waterproofing service is available in Bankstown. We focus most on balconies, basements, bathrooms and commercial roofs – the areas where Bankstown’s apartment towers, homes and businesses take on the most water.
Apartment towers
Bankstown’s CBD apartments have balconies stacked over living areas and retail below. A failed membrane at the door sill or drain soon shows up as ceiling stains and damaged finishes downstairs. We strip and re-membrane balconies properly, working with strata managers.
Basements
Basement car parks under Bankstown apartment and commercial buildings let water in through walls, slabs and joints. We seal below-ground structures in existing buildings and waterproof Dincel and retaining walls on new developments.
Homes & units
Leaking showers are the most common problem in Bankstown’s older homes and units. We repair failed membranes and waterproof new and renovated bathrooms to AS 3740, so water stays inside the shower and off the floors and walls.
Commercial
Shops, offices and mixed-use buildings around the Bankstown CBD often have flat concrete roofs and podiums. We re-membrane roofs that pond and leak, protecting tenants and stock below.
Long box gutters overflow inside when their lining fails. We seal gutters and outlets to keep water on the outside.
Lift pits waterproofed to stop seepage, standing water and corrosion that can damage lift equipment and trigger costly call-outs.
Laundry floors, tub areas and wall junctions sealed so constant moisture doesn't damage floors, skirting or the room next door.
Floor waterproofing for homes, units and businesses, applied with the right primer and system for concrete, screed or timber subfloors.
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.
Damp brickwork lets water track inside. We treat and seal masonry walls to keep moisture out for good.
Concrete pools and spas waterproofed so the shell holds water and the paving and ground around it stay dry.
Not sure where the water is coming from? We trace leaks through slabs, walls, showers and balconies before any work is quoted.
Every Bankstown job is done under Waterproofing Licence 36763C, so the work is recognised by insurers, certifiers and strata committees.
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 Bankstown 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.
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.
Whether it’s an apartment, a house or a shop, these are the warning signs we see most around Bankstown. Get them checked early.
A bathroom, balcony or roof above is leaking through the slab.
Groundwater is getting past below-ground walls or joints.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
Efflorescence means water is moving through the masonry.
Box gutters or roof outlets can’t cope and spill inside.
Four straightforward steps on every Bankstown job, from one unit to a whole building.
We visit your Bankstown property and trace the leak to its source.
You get the findings, the fix and the cost in writing.
We clean, repair and prime the substrate, then build up the membrane to the specified thickness.

We work across all of Bankstown – the CBD towers around Bankstown Central, the station and Paul Keating Park, the shops and offices on Chapel Road and North Terrace, and the residential streets beyond. Our Liverpool base is close by, so we’re in Bankstown every week.
