Copacabana NSW 2251
Looking for a professional waterproofing service in Copacabana? AB Sydney Waterproofing are experts in providing reliable residential, strata and commercial waterproofing across Copacabana NSW 2251. As licensed waterproofers in Copacabana, 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.
From beach houses and holiday homes to family homes on sloping blocks, the properties we waterproof in Copacabana and across the Central Coast 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.
Every job starts with finding out exactly where the water is coming from. We then recommend the simplest fix that will last – whether that’s tile injection, a remedial membrane or a full strip-out – and explain the options clearly before you decide.
From inside the bathroom to the roof and below ground, we waterproof it all in Copacabana. These four services are the ones we’re asked for most often.
Balconies
Balconies fail at the door sill, the drain and the balustrade fixings. Once water gets past the membrane it stains the ceiling below, lifts tiles and leaves white efflorescence on the soffit. We strip and re-waterproof balconies in Copacabana with UV-stable external membranes to AS 4654.
Wet areas
Whether you’re renovating or chasing a leak, the membrane under the tiles is what keeps water where it belongs. We install certified wet-area membranes with bond-breakers, reinforced corners and properly sealed penetrations, then issue a compliance certificate for your records.
Pools & spas
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.
Rooftops
From apartment rooftops to commercial roof decks and roof gardens, we install trafficable and non-trafficable membranes to suit how the roof is used, with box gutters and outlets sealed as part of the job.
Groundwater kept out of basements, garages and below-ground rooms with membranes suited to constant moisture pressure.
Long box gutters overflow inside when their lining fails. We seal gutters and outlets to keep water on the outside.
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.
Remedial floor membranes for wet areas, ground-floor slabs and commercial floors, matched to the substrate so water can't move through.
Shower leaking but tiles still solid? Resin injected through the grout lines can seal it in a day, without a full renovation.
Garden beds built against walls and over slabs are a common hidden leak. We waterproof and drain them properly.
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.
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.
Water damage gets more expensive the longer it runs. If you notice any of these, book a free inspection.
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.
More loss than evaporation usually means a failed membrane or joint.
