Storm crate

StormCrate55 modular cellular crates are used in storm water retention, attenuation and infiltration applications. The crates are designed to be simply and easily stacked together to create a below ground storm water holding tank or to allow the infiltration of storm water into the ground around them. The void created by the crates can then fill up with storm water during heavy rainfall conditions. The collected storm water then drains away slowly into the drainage system when the crate is used for attenuation, or, soaks away slowly into ground water table when the crate is used for infiltration.
Surface water Drainage

Surface Water offering includes a range of unperforated, perforated and half-perforated pipe in both solid wall Pvc and Twinwall Polyethylene pipework in diameters from 80mm-600mm. These systems are known for ease of installation, long-term reliability and guaranteed performance.
