Polystorm Lite modular geocellular structures can be used for the control and management of surface water. Polystorm Lite is unique in that it has been designed to withstand vertical loads of up to 20 tonnes meaning it makes the perfect solution for attenuation or soakaway applications in pedestrian or landscaped areas. Polystorm Lite modular cells are assembled together to form a structure of any shape of size to hold water either from roofs, gutters or surface drains.
The modular structure can then be wrapped in an impermeable membrane (attenuation) or permeable membrane (infiltration) to control the surface water entering the tank. The Polystorm Lite units are lightweight and easy to handle and have unique rounded corners to prevent punctures to the membrane during the installation process. With the use of a silt trap and Stormcheck Flow Control device, sediments can be removed before entering the tanks and then discharged at a set rate.
Polystorm Lite can also be used in conjunction with Polystorm and Polystorm Xtra to form a cost effective value engineered hybrid solution.
