Rockdale NSW 2216
Need dependable waterproofing in Rockdale? Our licensed team provides expert Rockdale waterproofing for houses, apartments, townhouses and commercial buildings. We repair leaking balconys, basements, bathrooms and more using proven membrane systems, with every job backed by a written 7-year warranty.
Properties across Rockdale and the wider bayside range from apartments along the main road to family homes. 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.
Our process is simple: a free inspection, a clear written quote, proper surface preparation, the right membrane applied at full thickness, and testing and certification at the end. No shortcuts, and no paying twice for the same leak.
We offer the full range of waterproofing in Rockdale, with particular focus on balcony, basement, bathroom and rooftop work – the areas where water causes the most damage when membranes fail.
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 Rockdale with UV-stable external membranes to AS 4654.
Below ground
Basements, garages and retaining walls hold back wet soil every day. Without a working membrane and drainage, water pushes through walls, slabs and joints. We waterproof Dincel, block and retaining walls on new builds in Rockdale and repair seepage in existing basements.
Showers & en-suites
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.
Rooftops
Roof leaks rarely come from the middle of the roof – they start at upstands, outlets, penetrations and junctions with walls. We detail every one of these properly, then apply a roof membrane that can handle Sydney’s heat, UV and heavy downpours.
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.
A properly sealed laundry floor and upturn protects floors, walls and neighbouring rooms from washing machine and tub leaks.
Floor waterproofing for homes, units and businesses, applied with the right primer and system for concrete, screed or timber subfloors.
Epoxy resin injected under existing tiles seals a leaking shower without demolition – a faster, lower-cost fix when the tiles are still sound.
Planter boxes and podium gardens lined with root-resistant membranes and proper drainage so they don't leak into walls or car parks.
External brick walls, parapets and chimneys treated against damp and salt so moisture stops reaching the inside of the building.
Concrete pools and spas waterproofed so the shell holds water and the paving and ground around it stay dry.
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.
Our free quote spells out the problem, the solution and the cost, so you can decide with all the facts.
Every job in Rockdale is backed by a written 7-year warranty. If something isn’t right, we come back and fix it.
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.
These are the early warning signs that waterproofing has failed. Catch them early and the repair is usually smaller.
A bathroom, balcony or roof above is leaking through the slab.
Efflorescence means water is moving through the masonry.
Groundwater is getting past below-ground walls or joints.
Water is passing through the wall instead of draining behind it.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
The same clear four steps on every Rockdale job, large or small.
We visit your Rockdale property and trace the leak to its source.
