Strathfield NSW 2135
Looking for a professional waterproofing service in Strathfield? AB Sydney Waterproofing are experts in providing reliable residential, strata and commercial waterproofing across Strathfield NSW 2135. As licensed waterproofers in Strathfield, 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.
Homes and buildings in Strathfield – apartments near the station to large Federation homes – all rely on waterproofing that’s hidden under tiles, screeds and coatings. When it fails, the first sign is usually a stain, a musty smell or a loose tile, and by then water has often been escaping for months.
We waterproof internal wet areas to AS 3740 and external areas to AS 4654, prepare every surface properly before the membrane goes on, and finish with a compliance certificate where required. That’s how we can back our work with a written 7-year warranty.
We offer the full range of waterproofing in Strathfield, with particular focus on balcony, bathroom, brick wall and pool work – the areas where water causes the most damage when membranes fail.
Terraces
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 Strathfield balcony drains properly and stays sealed.
Showers & en-suites
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 Strathfield to AS 3740, sealing floor wastes, corners and wall junctions properly.
Masonry
Salt marks, blistering render and mould low on internal walls all point to water moving through the masonry. We seal external walls and parapets and treat rising damp to stop the problem coming back.
Pools & spas
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 Strathfield – and waterproof new concrete pools before tiling.
Concrete roofs, roof gardens and trafficable decks protected with membranes designed for full sun, heat and heavy rain.
Dincel, block and retaining walls, basement slabs and car parks protected against groundwater and soil moisture.
We line and seal box gutters, sumps and outlets so heavy storms drain away instead of overflowing into the building.
Lift pits and shafts sealed against groundwater to protect lift equipment and stop corrosion in apartment and commercial buildings.
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.
Tile injection stops many shower leaks without ripping out the bathroom, so you avoid weeks of renovation.
Garden beds built against walls and over slabs are a common hidden leak. We waterproof and drain them properly.
Our inspection finds the real source of a leak first, so you only pay to fix what's actually failing.
Every Strathfield 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 Strathfield and nearby suburbs.

These are the early warning signs that waterproofing has failed. Catch them early and the repair is usually smaller.
A bathroom, balcony or roof above is leaking through the slab.
Efflorescence means water is moving through the masonry.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
Rising or penetrating damp is getting into the masonry.
More loss than evaporation usually means a failed membrane or joint.
