Leaking showers, balconies, roofs and basements fixed properly across Alexandria NSW 2015 – with a 7-year warranty and a free on-site inspection.
Alexandria NSW 2015
Looking for a professional waterproofing service in Alexandria? AB Sydney Waterproofing are experts in providing reliable residential, strata and commercial waterproofing across Alexandria NSW 2015. As licensed waterproofers in Alexandria, we find the real cause of every leak and fix it with long-lasting waterproofing membranes – backed by a 7-year warranty and a free on-site inspection.
Alexandria has changed faster than almost any suburb in Sydney. Former factory floors along Bourke Road and O’Riordan Street are now offices, showrooms and loft apartments, Victorian terraces still line the streets near Sydney Park, and the Green Square renewal has added thousands of new apartments with balconies, podium gardens and deep basement car parks. Each of these buildings needs a different kind of protection from water.
Much of Alexandria also sits on low, reclaimed ground around the Alexandria Canal, so groundwater and heavy summer storms put slabs, basements and box gutters under real pressure. We inspect first, find where the water is actually getting in, and fix the cause – not just the stain.
Bathrooms, balconies, rooftops and below-ground structures are where Alexandria’s terraces, apartments and warehouses take the most water – so these are the areas we give the closest attention to.
Wet areas
Shower and bathroom leaks affect 100-year-old Alexandria terraces and near-new apartments alike. Failed membranes, cracked grout and poorly sealed floor wastes let water into the floor below, the wall cavity and, in apartments, the unit downstairs.
Outdoor living
Alexandria’s newer apartment blocks have balconies stacked over living rooms and car parks. When the membrane fails at the door sill, balustrade or drain, water shows up as ceiling stains, drummy tiles or white efflorescence on the soffit below.
Roofs & gutters
Converted warehouses and commercial buildings in Alexandria often have flat concrete roofs and long box gutters that were never designed for modern storm intensity. We re-membrane roofs and gutters so they handle Sydney sun and downpours without leaking into the floor below.
Below ground
With a high water table around the Alexandria Canal and Green Square, below-ground structures take constant water pressure. We waterproof Dincel and block retaining walls and basement slabs on new builds, and repair seepage in existing car parks.
Laundries in Alexandria terraces are often squeezed into old rear additions with no proper membrane. We seal the floor, tub area and wall junctions so constant moisture doesn’t damage floors, skirting or the next room.
Remedial floor membranes for wet areas, ground-floor slabs and commercial floors, installed with the right primer and adhesive for the substrate so water can’t move through the slab.
Epoxy resin is injected under existing tiles to seal the leak without ripping out the bathroom – a fast, lower-cost fix for apartments where a full renovation isn’t practical.
Long box gutters on Alexandria warehouses and terraces overflow inside during storms. We re-membrane gutters and eaves so water runs off the roof, not into the walls.
Lift pits in apartment and commercial buildings sit below the water table. We seal pits and shafts against groundwater to protect lift equipment and stop corrosion.
Podium gardens and balcony planters are common in new Alexandria developments. Root-resistant membranes and proper drainage stop them leaking into car parks and units below.
Older brick terraces and warehouses suffer from rising and penetrating damp. We seal brick walls, parapets and chimneys to stop salt damage, flaking render and mould inside.
Membranes for concrete pools and spas in homes and residential complexes, applied before tiling or as a remedial fix for a pool that is losing water.
Not sure where the water is coming from? We trace leaks through slabs, walls, showers and balconies to find the source 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.
Every job is backed by a written 7-year warranty. If something isn’t right, we come back and fix it.
Water rarely shows up where it gets in. A free inspection traces the leak back to its source before we quote, so you pay to fix it once.
Internal wet areas are done to AS 3740 and external membranes to AS 4654, with a compliance certificate for your records, sale or strata.
From a single terrace bathroom to a warehouse roof or apartment block, we plan work around tenants, residents and business hours.
A free written quote that explains what’s wrong, the system we’ll use and the price – no surprises when the job is done.
Leaks get more expensive the longer they run. Call us for an inspection if you notice any of these – especially after one of Sydney’s heavy summer storms.

Water is sitting behind tiles or in the wall cavity.
