It’s a small angle at the shower entry. Most homeowners have never heard of it. Leave it out and the shower leaks into the room next door. What it does Water doesn’t only sit on top of your tiles. Some gets through the grout into the screed bed underneath – which is exactly what the…
Balconies usually tell you they’ve failed well before anyone connects the signs. In an apartment, the neighbour below often notices first. In a house, it turns up as a damp patch in a room nobody associates with the balcony. Here’s what to look for. On the balcony itself Tiles lifting, drumming or cracking, often along…
Long enough for the membrane to fully cure. Tiling early is one of the most common causes of waterproofing failure, and it’s completely avoidable. There isn’t one universal answer, because it depends on the system, the conditions and the substrate. The real answer is: whatever the product’s technical data sheet says, under the conditions on…
A waterproofing certificate is the document saying the wet area was done to standard, by a licensed contractor, using a specified system. It’s a small piece of paper that matters far more than people expect – at handover, at sale, and in any dispute afterwards. What it records The address and the specific areas waterproofed…
Rain isn’t the enemy. Standing water is. A flat roof is never truly flat – it’s built with a slight fall so water runs to an outlet. When water sits instead of draining, that’s ponding, and it’s one of the most common reasons roofs end up leaking. Why ponding causes problems Constant exposure. A membrane…
That white chalky residue isn’t a stain. It’s evidence that water is moving through your building. You’ll see it creeping out of grout lines on a balcony, running down a retaining wall, or blooming across a garage wall or basement floor. People scrub it off and it comes back, because scrubbing treats the symptom. What…
It’s the first question everyone asks, because it’s the difference between a repair and a renovation. The honest answer: if the membrane underneath has failed, yes. There is no way to repair a membrane you cannot reach. But that’s a bigger “if” than most people assume, and it’s worth finding out which situation you’re in…
Waterproofing done properly should last the life of the building. Bathrooms, balconies, roofs – all of it. If waterproofing has failed and the building isn’t old, it wasn’t done properly. That’s the honest answer, and it’s worth knowing before you accept the cost as inevitable. It’s a workmanship trade, not a product trade The membrane…
The short answer: it depends where the boundary sits in your strata plan – and that’s genuinely different building to building. We’re waterproofers, not lawyers, so treat this as how it usually plays out in practice rather than legal advice. For your specific building, your strata manager and your strata plan are the authority. The…
A leaking shower is rarely leaking where you think it is. Water runs. It gets through a gap, travels along the underside of a slab or down inside a wall cavity, and appears somewhere else entirely. That’s why so many shower repairs don’t work – the obvious spot gets sealed, and the actual defect is…
