Cavity Drainage System

Cavity Drainage Systems, often referred to as CDS, is a revolutionary approach to keeping your underground structures and building foundations dry. Unlike traditional methods, which may involve external excavation, the Cavity Drainage System is a proactive, internal solution.

 

The Cavity Drainage System works on a simple principle: it manages water ingress rather than trying to resist it. It allows water to enter the structure but ensures that it never causes any damage. This is achieved through a combination of specially designed membranes and drainage channels.

 

The membranes are applied to the walls and floors, creating a barrier that prevents water from entering the living space while allowing it to enter the cavity behind the membrane. This water then naturally flows into the drainage channels and is collected in a sump. From there, it is pumped out and safely disposed of, keeping your basement or underground areas dry and free from the damaging effects of water ingress.
