Cavity drain waterproofing systems take a different approach to managing water below ground.
Rather than trying to hold water back, they allow it to enter in a controlled way, before safely directing it to a drainage point.
This helps prevent pressure build-up and protects the internal structure over the long term.
BSSP supplies approved cavity drain systems, including membranes, drainage channels, pumps and ancillaries — giving you a complete, maintainable solution from one supplier.
These systems are widely used across basements, cellars, retrofit projects and new builds where a dry, habitable environment is required.
