Our Cavity Membrane is designed to allow the flow of hydrostatic ground water between the substrate and the membrane, whilst creating an airflow across it to prevent condensation. 

Watertight compression plugs are used to secure the membrane to the cellar walls whilst a sub-floor drainage channel is installed at the wall to floor joints connected into CellarPump.
