Cavity drain

A cavity drain system is an advanced waterproofing solution designed to manage water ingress in below-ground structures like basements and cellars. This system works by capturing and redirecting water that penetrates the external structure, ensuring a dry and habitable environment.

The system typically involves the installation of a cuspated membrane on the walls and floor. This membrane allows water to flow down to a perimeter drainage channel located at the wall-floor junction. The water is then directed to a sump pump or drainage outlet, where it is safely removed from the building.

One of the key advantages of a cavity drain system is its maintainability. Unlike other waterproofing methods that might require extensive repairs if they fail, cavity drain systems can be easily inspected and maintained. This makes them a reliable long-term solution for waterproofing.

Additionally, cavity drain systems are versatile and can be used in both new-build and refurbishment projects. They are particularly suitable for historic or listed buildings where minimal disruption is essential. The system also complies with British Standard 8102:2022, ensuring it meets high standards for waterproofing.

Overall, cavity drain systems provide a robust, maintainable, and efficient solution for managing water ingress in below-ground structures.
