Product Details

Polypipe Polystorm-R PSM1A is a cellular storage unit used to create underground attenuation or soakaway systems. They can be used in non-trafficked and trafficked areas such as car parks, driveways etc.

Minimum and maximum installation depths are determined by vertical loading (backfill and loads linked to operations) and horizontal loading (determined by the pressure exerted by the earth). This varies due to application and ground conditions. A structural design check of the system should be performed in line with CIRIA C680 prior to installation. This is provided free of charge from JDP Technical Support.
