Installation of the Soakaway and Attenuation Crates PSM1A

The Polystorm system is straight forward to install. The crates are supplied with clips which allows them to be held together securely and easily, as well as stability rods which ensure the crates do not slide on top of one another.

You then wrap the crates in Geotextile to hold the water, but allow some permeability.

Soakaway crates are available from our depots in Yorkshire, Cumbria and Warwickshire. If you have a special requirement or any questions, please contact us on 01430 430 529 or email
