Soakaway Crates

Stormwater Soakaway Crates

We supply a range of soakaway crates for the storage and attenuation of peak flow water discharge. Due to increased development, there is less permeable open ground for rain water to drain into. Additionally, there is a greater burden on drainage infrastructure due to an increase in flows to drains from buildings. This has lead to an increase in the frequency and severity of flooding in many regions of the UK. During periods of heavy rainfall, reduced permeability means that the ground is unable to absorb surface water fast enough, and the mains drainage system is unable to handle the increase in volume causing drains to overflow. In order to reduce extreme peak flows during heavy rainfall and thus reduce the risk of localised flooding, we offer the Stormwater Soakaway Crate.

The soakaway crates have a stackable modular design which combine to form a subterranean water infiltration or storage system. The entire structure is enclosed in geotextile membrane, which both filters and gradually releases water over a longer period of time, once the ground is ready to absorb it. The plastic crates have high void to volume ratio to maximise water retention, yet are robust and designed to withstand all types of vehicular traffic. 

FAQs

What are soakaway crates used for?

Soakaway crates can be used for infiltration systems and for water storage systems. Water storage tanks are lined with an impermeable geomembrane whereas infiltration tanks are lined with a permeable geotextile which allows water discharge through the membrane whilst preventing ingress of soil and sand particles.

Where can soakaway crates be installed?

Soakaway crates can be installed in trafficked areas (car parks, driveways etc.) or in landscaped areas subject to foot traffic.

How much cover do soakaway crates require?

The depth of cover required depends on the axle weight of trafficking vehicles.

Trafficked areas must be backfilled with well compacted sub-base material. Non-trafficked areas can be covered with excavated "as dug" material.
