Soakaway boxes are durable and strong and can be stacked both horizontally and vertically to create an effective soakaway underground drainage system. The Soakaway crates are used as part of an underground system where it is necessary to store or discharge a large volume of storm water as part of a complete soakaway system or attenuation (holding) system. The crates must be wrapped in a geotextile membrane which are available from Drainage365, to prevent the surrounding backfill material clogging up the soakaway boxes and reducing its effectiveness.
