From a single leaking bathroom to a full pool re-waterproof, we do it properly the first time across Gordon – licensed, certified and guaranteed for 7 years.
Gordon NSW 2072
Want a reliable waterproofing company in Gordon? AB Sydney Waterproofing delivers licensed waterproofing in Gordon 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.
Properties across Gordon and the wider upper North Shore range from large heritage homes on leafy blocks to apartments near the station. 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.
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.
From inside the bathroom to the roof and below ground, we waterproof it all in Gordon. These four services are the ones we’re asked for most often.
Showers & en-suites
Showers leak when the membrane is cracked, missing at the hob or wall junction, or wasn’t sealed around the floor waste. In Gordon we test, trace and repair the actual failure point – then re-waterproof to AS 3740 so the repair lasts as long as the tiles.
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 Gordon – and waterproof new concrete pools before tiling.
Basements
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.
Remedial roof membranes for homes, apartments and commercial buildings, built to handle UV, heat and heavy downpours.
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.
Laundries leak quietly behind machines and tubs. We waterproof the floor and walls properly so the problem doesn't come back.
Remedial floor membranes for wet areas, ground-floor slabs and commercial floors, matched to the substrate so water can't move through.
Tile injection stops many shower leaks without ripping out the bathroom, so you avoid weeks of 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.
Before any work is quoted, we pinpoint where the water is coming from – saving you from paying to fix the wrong thing.
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.
One leaking shower or a whole building – we scale the team and schedule to suit, with minimal disruption.
You’ll know the scope and price in writing before we start. The price we quote is the price you pay for that scope.
You get a written 7-year warranty on our workmanship, so you can renovate, rent or sell with confidence.
