Cavity drainage waterproofing systems refer to a technique used in construction to prevent water ingress into a building. It involves creating a cavity or void between the internal wall and an external waterproof membrane or tanking system. This cavity acts as a drainage channel, directing any water that enters the structure towards a sump or drainage point, allowing it to be safely removed from the building. The system typically includes the use of drainage and ventilation points, as well as the installation of a pump to remove excess water. Cavity drainage waterproofing systems are commonly used in basements and other below-ground structures, where the risk of water ingress is high.
