The tried and tested Polystorm geocellular range is designed to provide retention, attenuation or infiltration at a variety of depths. It is ideally suited to deeper applications and can accommodate a wide range of traffic loadings, from pedestrianised areas to largeView
Surface Water Infiltration
Where ground conditions are suitable, sustainable drainage systems (SuDS) can be used to manage and promote infiltration of surface water into the ground, replenishing natural water courses and aquifers.
Infiltration can be provided as part of either our Permavoid system (a shallow geocellular solution), our Polystorm system (a deep geocellular system) allowing surface water run-off to infiltrate into the ground, which would otherwise have been prevented by impermeable developments.
Either solution can be wrapped in a standard geotextile like Permatex 300 or a treatment geotextile such as Permafilter. Permafilter has been specifically designed to retain hydrocarbon pollutants and is capable of retaining up to 6L of oil per 10m².
This infiltration process also helps to prevent water sources and soils from drying out, thereby protecting local biodiversity and amenity.
