The simple and cost-effective drainage solution for cellars and basements
Cavity Membrane drainage system is a waterproof thermal insulating barrier that protects your cellar from dampness and moisture.
Manufactured from high density polyproplete cavity membrane is guaranteed for 20 years
Complies with building regulations for habitable living space
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.
