Failed waterproofing shows up as stained walls, musty basements, peeling paint and water pooling after every storm — and left alone it rots timber, corrodes steel and feeds mould. The fix is rarely one-size-fits-all: the right system depends on where the water is coming from, the substrate, and how much salt is in the masonry. We diagnose that first, then waterproof it properly so it lasts.
Sometimes water in a wall isn't a waterproofing problem at all — it's rising damp or subfloor moisture, which need a different fix, and it's often what's behind stubborn mould. We confirm the true source with a free damp inspection first, so you get the right treatment, not just the obvious one.
We find where the water's getting in, assess the substrate and salt load, and quote a fixed price.
Surface prep makes or breaks waterproofing. We prepare the substrate so the system bonds and lasts.
Membrane, tanking, crack injection or sealer — applied to AS 3740 (internal) and AS 4654.2 (external).
We make sure it's watertight and leave it clean, backed by our lifetime workmanship guarantee.
When waterproofing fails — in a basement, retaining wall, balcony or below-ground wall — water finds its way in continuously, not just when it rains. Left unaddressed, here's what follows.
Water is relentless — a small failure today becomes a structural problem later. Proper remedial waterproofing stops it at the source rather than chasing the symptoms inside.
Constant moisture in a basement or lower level creates exactly the damp, humid conditions mould needs. Damp and mould are well-recognised contributors to poor indoor air quality. Australian health authorities note that living in a damp or mouldy home is associated with a higher risk of respiratory issues such as coughing, wheezing and worsening asthma, along with eye, nose and throat irritation and allergic reactions — with children, the elderly and anyone with asthma or a weakened immune system most affected.
This is general information, not medical advice. If you're concerned about health symptoms, speak with your doctor.

Read our Google reviews →Yes. In many cases we can waterproof basement walls internally with tanking systems and crack injection, avoiding costly excavation. We assess each basement individually, since surface preparation and salt in the substrate strongly affect the right approach.
We cover basements, internal and external walls, balconies and retaining walls, using membranes, tanking, crack injection and sealers suited to each application.
Yes. Internal wet-area work follows AS 3740 and external above-ground waterproofing follows AS 4654.2, so the work is compliant and durable.
