Build Plumb Plastics offer a range of soakaway crates including Polypipe Polystorm, Polypipe Polystorm Lite and the Brett Martin StormCrate. These are all light-weight 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 agricultural applications.

Soakaway crates facilitate a quick and simple method of on-site assembly, where multiple configurations can be easily formed. A range of silt traps, flow control units and adaptors are also available to complete the system.

These soakaway boxes are manufactured to the same exacting standards as other high-quality brands such as the Osma soakaway crate, also referred to as Aquacell crates.

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

Brett Martin StormCrate dimensions are 1200mm Long x 600mm Wide x 420mm High

Each crate is supplied with the correct number clips and sheer connectors to aid installation. For a guide to installation and technical specification, please call or email our technical support team to request the appropriate brochure or download the Polypipe Polystorm technical installation guide and the Brett Martin StormCrate Installation Guide here.

Please note, the soakway crates we offer are ready built and not flat pack crates supplied by other manufacturers.

Build Plumb Plastics buy in bulk and are able to offer the cheapest price for soakaway crates. We will not be beaten on price or service! Please call us if you would like more information.

† The Polypipe Polystorm PSM1-A is a BBA approved and certified product. The Brett Martin Stormcrate is pending BBA approval and many other alternative soakaway products from other manufacturers do not have BBA approval. If you require a BBA approved soakaway system we recommend the Polystorm PSM1-A.
