Waterproofing

Membrane, detailing, curing time

Waterproofing failures almost never come from the middle of a wall. They come from junctions — where the floor meets the wall, around the waste, at the hob, behind the tap penetrations. Those are the points that need reinforcing, and they are the ones most often rushed.

We prime the substrate, install bond breakers at movement junctions, reinforce internal corners, then build the membrane up in coats to the required height — full-height in the shower, and up the walls elsewhere as the standard sets out. Then it gets left alone to cure before anything is tiled over it.

We work to AS 3740 for internal wet areas and AS 4654 for external above-ground work like balconies and terraces.

When something is already leaking

Water travels. A damp patch on a bedroom wall might be coming from a shower three metres away, a balcony above, or a failed junction around a window. Guessing is expensive, so we start by working out where it is actually getting in.

• Inspection of the wet area, penetrations and drainage
• Flood testing where the situation warrants it
• A written explanation of the cause, not just a price
• Repair options ranked by how permanent they are
• Reinstatement of tiling once the membrane is rebuilt

If a job is beyond a tiling and waterproofing fix — structural movement, a plumbing fault, roof or facade issues — we will say so and point you at the right trade rather than sell you a repair that will not hold.
