From a single leaking pool to a full basement re-waterproof, we do it properly the first time across Oatley – licensed, certified and guaranteed for 7 years.
Oatley NSW 2223
Looking for a professional waterproofing service in Oatley? AB Sydney Waterproofing are experts in providing reliable residential, strata and commercial waterproofing across Oatley NSW 2223. As licensed waterproofers in Oatley, we find the real cause of every leak and fix it with long-lasting membranes – backed by a free inspection and a written 7-year warranty.
Properties across Oatley and the wider St George area range from waterside homes on sloping blocks to units. Each brings its own waterproofing challenges – older wet areas built before modern membranes were required, outdoor areas exposed to sun and storms, and below-ground walls that hold back wet soil.
Because we hold Waterproofing Licence 36763C and certify our work to Australian Standards, our waterproofing is recognised by insurers, certifiers and strata committees – and it’s covered by a written 7-year warranty.
We offer the full range of waterproofing in Oatley, with particular focus on pool, basement, bathroom and balcony work – the areas where water causes the most damage when membranes fail.
Pools
A pool membrane protects more than the water level – it stops water soaking into the surrounding ground, paving and structure. We waterproof concrete pools and spas with flexible systems suited to constant immersion and pool chemicals.
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.
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.
Outdoor areas
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.
Concrete roofs, roof gardens and trafficable decks protected with membranes designed for full sun, heat and heavy rain.
We line and seal box gutters, sumps and outlets so heavy storms drain away instead of overflowing into the building.
Positive and negative-side membranes for lift pits that sit below the water table, on new builds or as a remedial fix.
A properly sealed laundry floor and upturn protects floors, walls and neighbouring rooms from washing machine and tub leaks.
Remedial floor membranes for wet areas, ground-floor slabs and commercial floors, matched to the substrate so water can't move through.
Epoxy resin injected under existing tiles seals a leaking shower without demolition – a faster, lower-cost fix when the tiles are still sound.
Planters and garden beds against walls or over slabs waterproofed and drained so roots and water stay where they belong.
Brick walls, parapets and chimneys sealed against rising and penetrating damp to stop salt damage, flaking render and mould inside.
Before any work is quoted, we pinpoint where the water is coming from – saving you from paying to fix the wrong thing.
Every Oatley 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 Oatley and nearby suburbs.

These are the early warning signs that waterproofing has failed. Catch them early and the repair is usually smaller.
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.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
A bathroom, balcony or roof above is leaking through the slab.
