The Permavoid system comprises of high strength modular cells suitable for sub-base replacement, plus components that incorporate silt / oil treatment and shallow flow controls into the system.
It can be used in place of a traditional aggregate sub-base within trafficked pavements, providing a unique high strength, consistent structural raft in accordance with BS7533-13:2009. The geocellular structures have a void ratio up to 95%, greatly enhancing the pavement's attenuation capacity and reducing aggregate requirements in hydraulic pavements. The system is suitable beneath asphaltic, block-paved or concrete pavements and for the full range of traffic conditions from domestic driveways to highways.

Permavoid is an engineered system of high strength modular cells, interlocked to create a structural raft with exceptionally high tensile and compressive strength under load.
The Permavoid system is designed to be used in place of traditional aggregate sub-base, providing a unique, high strength, consistent structural raft with all the benefits of a high voided modular geocellular structure.
The Permavoid System comprises of a number of components which may be utilised within a SuDS design
