A special grade of GeoGrid developed with the UK's market-leading grid supplier, Marshalls HX165 Grid provides additional stability within the sub-base of a Priora permeable pavement.
Installed directly over the subgrade, the profile of the ribs and the shape of the apertures have been specially developed to maximise interlock with Marshalls' angular Priora aggregate, confining movement and improving the CBR of the ground by 1%.
This can drive cost from the system, or in situations where excavation depth is an issue (such as city centres), it could make a permeable system possible where it wasn't before.
