A range of high performance profiled plastic drainage systems for water management. The systems are designed to control and discharge water entering a structure, in full accordance with BS81902:2009 Type C (drained) protection.
For more information about our cavity drainage systems and channel drainage, contact the RIW Technical Department.
- Cavity DrainCavity Drain R20 & R7 are used as internal cavity drainage membrane systems, to collect water entering the structure. Cavity Drain R20 and R7 are typically used in basements and sub-structures, to channel water ingress to a sump or collection point for disposal.
- Double DrainDouble Drain is a cold applied, high density polyethylene profiled sheet, incorporating a permeable geotextile filter fabric, designed to prevent ground water reaching the structure.
- Plaster DrainPlaster Drain is an internal drainage membrane, used to channel water ingress to a sump or collection point for disposal or to separate new finishes from a damp wall.
- Sump Pumps/Aqua ChannelCavity drainage systems are designed to be fully maintainable, as this is a requirement for Type C (drained) protection as outlined in BS 8102:2009 Code of practice for protection of below ground structures against water from the ground.
