A Geocellular Solution for shallow applications

Permavoid can be used as part of an engineered or soft SuDS solution, enabling designers to offer an effective source control system, that can incorporate water treatment to manage water volume and quality as close as possible to where rainfall lands.

Silt/debris and hydrocarbons can be managed at the head of the system using system components, such as RIDGISTORMSeparate Silt Traps. This prevents pollution migration into the rest of the SuDS and reduces lifetime maintenance requirements.

Shallower attenuation or infiltration structures are often necessary because the site is difficult to access or the ground at greater depths presents a construction challenge, such as chemical contamination, a high water table or hard rock substrate. A shallower approach also minimises the need for expensive pumping equipment, and reduces environmental impact because it requires less excavation and fewer trips to transport infill and rubble to and from site.
