Description

The most prevalent size for residential soakaways is the 1m³ variant, aligning with the specifications of numerous local authorities. With the capacity to effectively drain around 50m² of roofing area under standard ground conditions, the 1m³ soakaway is an excellent choice.

This StormCrate is an innovative modular geo-cellular unit designed for underground stormwater attenuation, surface water infiltration and soakaway systems. The crates interlock to create a substantial below-ground holding chamber or to facilitate stormwater infiltration into the adjoining earth.
