Maroubra NSW 2035
Need dependable waterproofing in Maroubra? Our licensed team provides expert Maroubra waterproofing for houses, apartments, townhouses and commercial buildings. We repair leaking balconys, bathrooms, rooftops and more using proven membrane systems, with every job backed by a written 7-year warranty.
Like much of the eastern suburbs, Maroubra is a mix of beachside apartments and units to family homes. Whatever the building, water finds the weakest point – a cracked grout line, a failed door sill, a blocked outlet or an unsealed joint – and the damage often shows up a long way from where the water gets in.
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.
Every waterproofing service is available in Maroubra. Balcony, Bathroom, Rooftop and Brick Wall waterproofing get our closest attention, because they’re the jobs Maroubra property owners call us for most.
Outdoor areas
Water should run off a balcony, not sit on it. We check falls, outlets and thresholds first, fix any ponding, then apply a flexible external membrane with reinforced corners and properly sealed upstands – so your Maroubra balcony drains properly and stays sealed.
Showers & en-suites
Most bathroom leaks start at the same few weak points: cracked grout, a poorly sealed floor waste, or a membrane that stops short at the wall. We find exactly where water is escaping and fix it – with tile injection when the tiles are sound, or a new membrane when they’re not.
Flat roofs
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.
Brickwork
Masonry is porous, and without proper damp-proofing it acts like a sponge. We work out whether the moisture is rising, penetrating or coming from poor drainage, then treat it with the right system for the wall.
Below-ground waterproofing for new builds and remedial seepage repairs in existing basements and garages.
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.
A properly sealed laundry floor and upturn protects floors, walls and neighbouring rooms from washing machine and tub leaks.
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.
Membranes for concrete pools and spas, applied before tiling on new pools or as a remedial fix for a pool that's losing water.
Before any work is quoted, we pinpoint where the water is coming from – saving you from paying to fix the wrong thing.
Every Maroubra job is done under Waterproofing Licence 36763C, so the work is recognised by insurers, certifiers and strata committees.
We work for homeowners, landlords, builders, strata managers and businesses across Maroubra and nearby suburbs.
A free written quote that explains what’s wrong, the system we’ll use and the price – no surprises when the job is done.
Our waterproofing comes with a 7-year written warranty – long after the tiles go down, we still stand behind the work.
Water rarely shows up where it gets in. A free inspection traces the leak to its source before we quote, so you pay to fix it once.
Wet areas are waterproofed to AS 3740 and outdoor areas to AS 4654, and you receive a compliance certificate when we finish.
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.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
Box gutters or roof outlets can’t cope and spill inside.
Rising or penetrating damp is getting into the masonry.
