Want a reliable waterproofing company in Sans Souci? AB Sydney Waterproofing delivers licensed waterproofing in Sans Souci for every part of your property, from wet areas inside to balconies, roofs and below-ground walls outside. We inspect first, explain what’s failing and fix it properly.
Homes and buildings in Sans Souci – waterside homes to units – all rely on waterproofing that’s hidden under tiles, screeds and coatings. When it fails, the first sign is usually a stain, a musty smell or a loose tile, and by then water has often been escaping for months.
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 Sans Souci. These four services are the ones we’re asked for most often.
Pools
A pool membrane protects more than the water level – it stops water soaking into the surrounding ground, paving and structure. We waterproof concrete pools and spas with flexible systems suited to constant immersion and pool chemicals.
Terraces
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 Sans Souci balcony drains properly and stays sealed.
Wet areas
Showers leak when the membrane is cracked, missing at the hob or wall junction, or wasn’t sealed around the floor waste. In Sans Souci we test, trace and repair the actual failure point – then re-waterproof to AS 3740 so the repair lasts as long as the tiles.
Basements
Below-ground waterproofing has to resist constant water pressure, so the system matters. We use membranes suited to the wall type and conditions – applied before backfill on new builds, or from the inside where excavation isn’t practical.
Concrete roofs, roof gardens and trafficable decks protected with membranes designed for full sun, heat and heavy rain.
Box and eaves gutters re-membraned so storm water runs off the roof instead of spilling into walls and ceilings.
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.
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.
Planter boxes and podium gardens lined with root-resistant membranes and proper drainage so they don't leak into walls or car parks.
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.
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.
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.
These are the early warning signs that waterproofing has failed. Catch them early and the repair is usually smaller.
More loss than evaporation usually means a failed membrane or joint.
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.
Groundwater is getting past below-ground walls or joints.
The same clear four steps on every Sans Souci job, large or small.

If you’re topping up much more often than usual in mild weather, or notice damp ground, cracks or loose tiles around the pool, it’s worth an inspection.
Most balcony leaks start at the door sill, the drain or the balustrade fixings, where the membrane has cracked or was never properly detailed. We find the failure point and re-waterproof the balcony properly.
Prices vary with the area, access, the condition of the surface and the system required. We inspect for free and give you a written quote, so there’s no guessing before you commit.
