Certified membranes, honest advice and a written 7-year warranty. We waterproof pools, bathrooms and basements across Menai and nearby suburbs.
Menai NSW 2234
Looking for a professional waterproofing service in Menai? AB Sydney Waterproofing are experts in providing reliable residential, strata and commercial waterproofing across Menai NSW 2234. As licensed waterproofers in Menai, 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 Menai and the wider Sutherland Shire range from family homes on sloping blocks to townhouses. 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.
Every waterproofing service is available in Menai. Pool, Bathroom, Basement and Balcony waterproofing get our closest attention, because they’re the jobs Menai property owners call us for most.
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.
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 Menai to AS 3740, sealing floor wastes, corners and wall junctions properly.
Retaining walls
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
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.
Laundry floors, tub areas and wall junctions sealed so constant moisture doesn't damage floors, skirting or the room next door.
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.
Planters and garden beds against walls or over slabs waterproofed and drained so roots and water stay where they belong.
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.

The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
Groundwater is getting past below-ground walls or joints.
