StormCrate55 - Stormwater Retention, Attenuation & Infiltration Crate

Price on Application

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. Extensive use of this type of storm water attenuation/ infiltration module has helped relieve pressure on conventional surface water drainage systems in line with the Sustainable Urban Drainage Systems (SUDS) program advocated by the Environment Agency.


  • StormCrate55 provide a highly effective means of managing storm water, contributing to reducing the risk of flooding.
  • Rainwater Infiltration: StormCrate55 can be wrapped in a geotextile which allows stored water to slowly seep into the surrounding ground and back into the water table.
  • Rainwater Attenuation: another common practice is to surround StormCrate55 with an impermeable geomembrane to create a sealed underground tank. The outlet from this tank is then controlled to facilitate a slow release of the stored water back into the drainage system over a longer period.
