Permavoid stores water at source for irrigation

Net zero system from Polypipe features a raft of connecting water storage cells that sits beneath highways or hard landscaping to feed nearby trees and plants in dry spells

Permavoid is a breakthrough shallow invert geocellular sub-base replacement system designed to manage surface water at source. 

Cells are interconnected using geometric ties to create a uniform structural raft with exceptionally high load-bearing characteristics. Having the ability to store water safely immediately beneath a finished surface allows a Permavoid raft to be used for irrigation.

Urban greening such as a blue-green roof or surface planting across a public realm can be sustained by drawing stored water from the raft through special wicking cones to the soil above. 

This unique, net zero feature enhances resilience - preserving plants and ecosystems through extended dry spells - improves community health, reduces the heat island effect and lowers overall potable water consumption.

Manufactured from 100 per cent recycled polymer, Permavoid can be used to attenuate and manage water at roof, podium or ground level. 

Its shallow invert makes it ideal for projects where there is a high water table, contaminated brownfield land or where there is a shallow outfall - a situation where conventional deep buried surface water storage tanks would require additional pumping.

Permavoid can also be adapted to provide high performance surface water treatment of hydrocarbons, heavy metals and contaminated silts.
