Want a reliable waterproofing company in Heathcote? AB Sydney Waterproofing delivers licensed waterproofing in Heathcote 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.
From bushland-edge homes on sloping blocks to family homes, the properties we waterproof in Heathcote and across the Sutherland Shire vary a lot. What doesn’t change is our approach: inspect carefully, find the cause, and use a membrane system that suits the surface, the exposure and how the space is used.
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 Heathcote. These four services are the ones we’re asked for most often.
Basements
Basements, garages and retaining walls hold back wet soil every day. Without a working membrane and drainage, water pushes through walls, slabs and joints. We waterproof Dincel, block and retaining walls on new builds in Heathcote and repair seepage in existing basements.
Bathrooms
A failed shower membrane lets water into the floor, wall frames and the room or unit below – often for months before you see a stain. We repair leaking showers and waterproof new and renovated bathrooms in Heathcote to AS 3740, sealing floor wastes, corners and wall junctions properly.
Outdoor areas
Water should run off a balcony, not sit on it. We check falls, outlets and thresholds first, fix any ponding, then apply a flexible external membrane with reinforced corners and properly sealed upstands – so your Heathcote balcony drains properly and stays sealed.
Pools
Pools lose water through cracked shells, failed construction joints and leaking fittings. We find which one it is, repair it properly and apply a pool-grade membrane suited to constant immersion and chlorinated water.
Flat concrete roofs and roof decks re-membraned so they shed water instead of ponding and leaking into the floor below.
Long box gutters overflow inside when their lining fails. We seal gutters and outlets to keep water on the outside.
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.
Concrete and screed floors waterproofed for wet areas, ground floors and commercial spaces where water must stay out of the slab.
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.
Brick walls, parapets and chimneys sealed against rising and penetrating damp to stop salt damage, flaking render and mould inside.
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.
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.
Every job in Heathcote 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.
