Bridge the cracks before they bridge your membrane.
Every membrane failure starts at a movement joint. Wherever two surfaces meet — wall to floor, slab to upstand, around a pipe or a drain — they will move independently as the building settles, heats and cools. A liquid membrane painted straight across that joint will crack within months. Reinforcement tapes and mesh exist to bridge these joints so the membrane stays continuous, even as the substrate shifts beneath it.
Our range covers the three formats you actually need on site. Bond breaker tape (typically 50mm or 100mm polyester or butyl) decouples the membrane from the joint so it can stretch instead of tear. Reinforcement fabric — a non-woven polyester scrim — is embedded in the first membrane coat across corners, junctions and outlets, doubling the film thickness exactly where it's stressed most. Fibreglass mesh is used with cementitious systems and over crack-prone substrates like fibre cement sheeting to distribute load and prevent stress concentration.
These aren't optional add-ons. AS 4858 and the membrane manufacturer's installation guide both require detailing tape at internal corners, around penetrations and across construction joints. Skipping this step is the single most common reason a membrane fails its flood test, and the most common defect found in independent waterproofing inspections.
Stock all three formats on the truck before you start. They're cheap, they're light, and they're the difference between a job that gets signed off first time and a callback in 18 months when the tiles start lifting.
