Polystorm and Polystorm Lite are lightweight modular water storage cells with a high void ratio that can be used for either attenuation or infiltration of stormwater in residential, commercial, industrial and retail applications. The system facilitates quick and easy assembly on site where multiple configurations can be formed from standard stock items. A full range of silt traps, flow control units and adaptors complete the system.

Polystorm soakaway boxes are manufactured to the exacting standards of Osma's soakaway crate, otherwise known as Aquacell.Please call or email for a specification brochure.

5 number of Polystorm soakaway crates equals 1 cubic metre of soakaway. One crate should be used for every 10 square metres of roof area to be drained.

Each crate is supplied with 4 clips and 2 shear band connectors. We buy in bulk and will not be beaten on price or service! Please call us if you would like more information.

Polystorm dimensions are 1000mm Long x 500mm Wide x 400mm High, giving a 95 % Void Ratio.
