🏗️ A SMARTER WAY TO BUILD YOUR CAVITY WALL
When every millimetre matters, why make your walls wider than they need to be?
SureCav create a clean, protected cavity without traditional concrete backing blocks.
🔹 Maximise insulation space
SureCav25 helps maintain a 100mm overall cavity while allowing more room for insulation.
🔹 Keep the cavity clean
Helps prevent mortar and debris from entering the cavity and interfering with wall ties.
🔹 Protection from wind-driven rain
Creates a barrier to help protect the inner leaf from moisture ingress.
🔹 Lightweight & easy to handle
A practical alternative to heavy backing blocks.
Ideal for new builds, extensions, brickwork and stonework.
