Polystorm Soakaway Crates

Soakaway crates, (also known as storm cells or attenuation cells) are a fantastic water management solution to help reduce the risk of flooding.

Storm crates are designed to provide attenuation or soakaway at a variety of depths and to accommodate a wide range of traffic loadings, from pedestrianised areas to large HGV parks. Our extensive range of storm crates are available for a variety of commercial and residential needs. The primary brands we stock are Polystorm and Rainbloc.

Our storm crates are light, easy to assemble and connect together, therefore enabling you to create your required structure. The outer surfaces of the crates should be wrapped in geotextile membrane, which stops soil from entering and clogging up the system. Please visit our Geotextile page to find out more.
