Marshalls MG15 Grid
Marshalls MG15 Grid has been specially developed to stabilise the sub-base of a Priora System. Inclusion of a grid has the effect of improving the CBR by 1% (on subgrades of 1% - 4%), which in many case will reduce the depth of the system.
This can drive cost from the system, or in situations where excavation depth is an issue (city centres, for example), it could make a permeable system a possibilty where it wasn't before.
The profile of the ribs and the shape of the apertures has been specially developed to maxmise interlock with Marshalls angular Priora aggregate.
