  • StormCrate55 soakaway crates 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.
