Finesse Cavidrain is a preformed cavity drainage system designed to relieve water penetration from basements, buried structures and underground car parks.  Suitable for new and existing structures.

Traditional methods of ground water exclusion are difficult to install reliably in the modern deep basement with piled slabs and secant piled walls.  Cavidrain is a waterproofing system that enables fast track construction by eliminating wet trades and removing the waterproofing installation from the critical path.

Cavidrain maximises the available internal space.  It is very easily and quickly installed, making Cavidrain a very cost effective waterproofing system.

Tunnel Drainage

Finesse Cavidrain provides a drainage layer to collect infiltration water from behind tunnel linings.  Cavidrain may be used alone or form part of a system incorporating geomembranes.  Typically the Cavidrain is fixed to the excavated face of the tunnel.  Shotcrete will adhere to the back of the Cavidrain sheet.  Cavidrain is used in road tunnels, mine shafts, interceptor sewers, etc.
