List of featured suppliers of CAVITY DRAINAGE Systems on Building Products Index
Cavity drainage systems refer to a technique used to waterproof buildings by creating a void or cavity between the internal and external walls. The system is designed to channel any water that penetrates the outer layer of the building down into a sub-floor drainage channel, and then away from the building. This method is most commonly used in below-ground structures, such as basements and cellars, to prevent water ingress and associated damage.
