Polystorm Geocellular System

Polystorm Geocellular System for Deep Applications

The tried and tested Polystorm geocellular range is designed to provide surface water retention, surface water attenuation or surface water infiltration at a variety of depths. It is ideally suited to deeper applications and can accommodate a wide range of traffic loadings, from pedestrianised areas to large HGV parks.


The Polystorm geocelluar system can also be integrated with Permavoid systems.

The modular cells combine to provide water storage structures to help with localised flood alleviation and surface water management. Each cell has a 95% void ratio and provides a highly efficient water retention, attenuation or infiltration solution.


Polystorm Geocellular Features & Benefits

  • 95% void ratio providing greater water storage capacity with reduced excavation and disposal costs
  • 3D flow throughout the structure removes the need for distribution pipes
  • Access for inspection and maintenance can be facilitated by the inclusion of Polystorm Access and Inspect
  • BBA Approval for Polystorm-RPolystorm Lite and Polystorm. BBA pending for Polystorm Xtra
