Need professional commercial waterproofing in Chatswood? AB Sydney Waterproofing provides licensed waterproofing services in Chatswood for apartment towers, office buildings, retail centres and homes. We waterproof balconies, podiums, basements, lift pits and roofs with proven systems – with a free inspection and a written 7-year warranty.
Chatswood is the North Shore’s major commercial centre. High-rise apartments and office towers surround Chatswood station, Westfield and Chatswood Chase, with The Concourse and Victoria Avenue at the heart of the CBD. Beyond the centre, heritage conservation areas protect streets of Federation and inter-war homes.
Tall buildings bring complex waterproofing: stacked balconies, podium gardens over retail, deep basements and lift pits, and large roof plant areas. We work with building managers, strata committees and facility managers, plan access and safety carefully, and keep disruption to residents and tenants low.
Every waterproofing service is available in Chatswood. Balconies, basements, roofs and bathrooms get our closest attention – the areas Chatswood’s towers, offices and homes depend on most.
High-rise
Chatswood’s towers have hundreds of balconies stacked above each other and podium terraces over shops and car parks. A failed membrane can send water down several levels. We re-waterproof balconies and podiums with careful detailing at every sill, drain and planter.
Basements
Deep basements under Chatswood’s towers and retail centres face constant groundwater pressure. We seal walls, slabs and construction joints in existing basements, waterproof lift pits, and waterproof Dincel and retaining walls on new developments.
Commercial roofs
Office and apartment roofs in Chatswood carry plant equipment, roof gardens and communal terraces. We re-membrane roofs and plant decks so they handle foot traffic, equipment and heavy storms without leaking into the floors below.
Apartments & homes
From en-suites in high-rise apartments to bathrooms in heritage homes, leaking showers cause damage that spreads quickly. We repair failed membranes and waterproof new bathrooms to AS 3740.
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.
Epoxy resin injected under existing tiles seals a leaking shower without demolition – a faster, lower-cost fix when the tiles are still sound.
Garden beds built against walls and over slabs are a common hidden leak. We waterproof and drain them properly.
External brick walls, parapets and chimneys treated against damp and salt so moisture stops reaching the inside of the building.
Membranes for concrete pools and spas, applied before tiling on new pools or as a remedial fix for a pool that's losing water.
Our inspection finds the real source of a leak first, so you only pay to fix what's actually failing.
We hold Waterproofing Licence 36763C and put our name to every membrane we install – no unlicensed subcontractors.
We test and trace the leak first, so the quote covers what’s actually failing – not guesswork.
We follow AS 3740 inside and AS 4654 outside, and hand over the paperwork your certifier, insurer or buyer will ask for.
From a single bathroom to a full apartment block or commercial roof, we plan work around residents, tenants and business hours.
Our free quote spells out the problem, the solution and the cost, so you can decide with all the facts.
Every job in Chatswood is backed by a written 7-year warranty. If something isn’t right, we come back and fix it.
Whether you manage a tower or own a single apartment, these are the warning signs we see most in Chatswood.
A bathroom, balcony or roof above is leaking through the slab.
Groundwater is getting past below-ground walls or joints.
Box gutters or roof outlets can’t cope and spill inside.
The bond has failed because the bed underneath is wet.
Efflorescence means water is moving through the masonry.
Water is sitting behind tiles or inside the wall cavity.
Four clear steps on every Chatswood job – from one apartment to a whole tower.
We visit your Chatswood property and trace the leak to its source.
A written, itemised quote with no obligation.
Proper preparation first – cracks repaired, corners and joints reinforced – then the membrane goes on.
We test, hand over the compliance certificate and register your 7-year warranty.
We cover all of Chatswood – the apartment and office towers around the station, Westfield, Chatswood Chase and Victoria Avenue, and the heritage homes in the surrounding conservation areas. Our team works across the North Shore every week.
