Want a reliable waterproofing company in Wolli Creek? AB Sydney Waterproofing delivers licensed waterproofing in Wolli Creek for every part of your property, from wet areas inside to balconies, roofs and below-ground walls outside. We inspect first, explain what’s failing and fix it properly.
Like much of the inner south, Wolli Creek is a mix of high-rise apartment towers and mixed-use buildings. Whatever the building, water finds the weakest point – a cracked grout line, a failed door sill, a blocked outlet or an unsealed joint – and the damage often shows up a long way from where the water gets in.
Our process is simple: a free inspection, a clear written quote, proper surface preparation, the right membrane applied at full thickness, and testing and certification at the end. No shortcuts, and no paying twice for the same leak.
Every waterproofing service is available in Wolli Creek. Basement, Balcony, Rooftop and Floor waterproofing get our closest attention, because they’re the jobs Wolli Creek property owners call us for most.
Below ground
Water pressure behind a wall never stops, so below-ground waterproofing has to be continuous – walls, slab and the joint between them. We seal construction joints and penetrations, then apply a membrane designed for constant moisture.
Terraces
A balcony over a living room or garage needs a membrane that handles full sun, heavy rain and movement. We prepare the slab properly, correct falls where needed, and detail every edge, outlet and threshold so water drains away instead of finding its way inside.
Roofs & decks
From apartment rooftops to commercial roof decks and roof gardens, we install trafficable and non-trafficable membranes to suit how the roof is used, with box gutters and outlets sealed as part of the job.
Commercial floors
From kitchens and wash-down areas to workshops and amenities, floors take water every day. We prepare the slab properly and apply durable systems that stop water reaching the structure or the space below.
Leaking showers repaired and new bathrooms waterproofed with certified membranes, so water stays in the shower and out of the structure.
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.
A properly sealed laundry floor and upturn protects floors, walls and neighbouring rooms from washing machine and tub leaks.
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.
Brick walls, parapets and chimneys sealed against rising and penetrating damp to stop salt damage, flaking render and mould inside.
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.
We hold Waterproofing Licence 36763C and put our name to every membrane we install – no unlicensed subcontractors.
Every job in Wolli Creek is backed by a written 7-year warranty. If something isn’t right, we come back and fix it.
We test and trace the leak first, so the quote covers what’s actually failing – not guesswork.
We follow AS 3740 inside and AS 4654 outside, and hand over the paperwork your certifier, insurer or buyer will ask for.
From a single bathroom to a full apartment block or commercial roof, we plan work around residents, tenants and business hours.
Our free quote spells out the problem, the solution and the cost, so you can decide with all the facts.
