Leaking bathroom, pool or basement? We find the real cause and fix it with the right membrane – licensed, with a free inspection and a 7-year warranty.
Lucas Heights NSW 2234
Looking for a professional waterproofing service in Lucas Heights? AB Sydney Waterproofing are experts in providing reliable residential, strata and commercial waterproofing across Lucas Heights NSW 2234. As licensed waterproofers in Lucas Heights, 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 Lucas Heights – family homes to townhouses – 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 Lucas Heights, with particular focus on bathroom, pool, basement and balcony work – the areas where water causes the most damage when membranes fail.
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.
Backyard 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 Lucas Heights – and waterproof new concrete pools before tiling.
Below ground
Below-ground waterproofing has to resist constant water pressure, so the system matters. We use membranes suited to the wall type and conditions – applied before backfill on new builds, or from the inside where excavation isn’t practical.
Balconies
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 Lucas Heights balcony drains properly and stays sealed.
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.
Lift pits and shafts sealed against groundwater to protect lift equipment and stop corrosion in apartment and commercial buildings.
Laundries leak quietly behind machines and tubs. We waterproof the floor and walls properly so the problem doesn't come back.
Concrete and screed floors waterproofed for wet areas, ground floors and commercial spaces where water must stay out of the slab.
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.
Damp brickwork lets water track inside. We treat and seal masonry walls to keep moisture out for good.
Not sure where the water is coming from? We trace leaks through slabs, walls, showers and balconies before any work is quoted.
Every Lucas Heights job is done under Waterproofing Licence 36763C, so the work is recognised by insurers, certifiers and strata committees.

These are the early warning signs that waterproofing has failed. Catch them early and the repair is usually smaller.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
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.
