Podium Deck RWP Chamber


Rainwater or drainpipes can be easily connected to Permavoid infiltration or storage and conveyance systems on multifunctional green roofs, podium decks or SUDS.


The RWP chamber is designed for use in shallow Permavoid podium deck constructions; the Podium Deck RWP Chamber collects rainwater from the inlet pipe, filters the water through the perforated walls and dispersed it into the surrounding Permavoid storage system. The Podium Deck RWP chamber is compatible with standard 110mm Ø or 160mm Ø push fit couplings and has been designed to properly cope with flow speeds and quantities pertaining to the standard 110mm Ø inlet pipe.

“The units are designed with tomorrow’s  world in mind. Made from 100% recycled  materials now, and again 100% recyclable  in  the future.”

Ron van Raam, CEO Permavoid
