Want a reliable waterproofing company in Engadine? AB Sydney Waterproofing delivers licensed waterproofing in Engadine 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.
From family homes on bushland-edge blocks to townhouses and villas, the properties we waterproof in Engadine and across the Sutherland Shire vary a lot. What doesn’t change is our approach: inspect carefully, find the cause, and use a membrane system that suits the surface, the exposure and how the space is used.
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.
We offer the full range of waterproofing in Engadine, with particular focus on bathroom, pool, basement and balcony work – the areas where water causes the most damage when membranes fail.
Wet areas
A failed shower membrane lets water into the floor, wall frames and the room or unit below – often for months before you see a stain. We repair leaking showers and waterproof new and renovated bathrooms in Engadine to AS 3740, sealing floor wastes, corners and wall junctions properly.
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.
Below ground
Water pressure behind a wall never stops, so below-ground waterproofing has to be continuous – walls, slab and the joint between them. We seal construction joints and penetrations, then apply a membrane designed for constant moisture.
Terraces
Leaking balconies are one of the most common strata repairs we do. We re-waterproof balconies and terraces with minimal disruption, keep residents and managers informed, and provide a written warranty for the owners’ corporation records.
Flat concrete roofs and roof decks re-membraned so they shed water instead of ponding and leaking into the floor below.
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.
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.
Planters and garden beds against walls or over slabs waterproofed and drained so roots and water stay where they belong.
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.
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.
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.
These are the early warning signs that waterproofing has failed. Catch them early and the repair is usually smaller.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
More loss than evaporation usually means a failed membrane or joint.
Groundwater is getting past below-ground walls or joints.
Water is passing through the wall instead of draining behind it.
A bathroom, balcony or roof above is leaking through the slab.
The same clear four steps on every Engadine job, large or small.
We visit your Engadine property and trace the leak to its source.
You get the findings, the fix and the cost in writing.
We clean, repair and prime the substrate, then build up the membrane to the specified thickness.
Wet areas are flood tested where suitable, then certified and covered by our warranty.

Often, yes. If the tiles are still well bonded, tile injection seals the leak from underneath without demolition. If the membrane has failed completely, we’ll explain why a strip-out is the better long-term fix.
Yes. Re-tiling is the ideal time to repair the shell and apply a new pool membrane, so the new tiles aren’t hiding an old leak.
Most shower and balcony repairs take a few days including curing time; tile injection is usually done in a day. Larger roofs, basements and strata jobs are scheduled in stages – we’ll give you a timeframe with your quote.
Yes. Every job comes with a written 7-year warranty on workmanship, plus a compliance certificate for wet areas – useful for insurance, strata and future sales.
