Installing A Type C Priora Pavement

This video shows how to create a tanked sub-base for a Marshalls Priora system. This may be necessary where ground conditions don’t allow infiltration, or where you don’t want contaminated ground to leach into the Priora sub-base. Using just two different grades of easily available aggregate and MM380 Tanking Membrane you can create a Sustainable Drainage System which, when covered with Marshalls Priora blocks, can withstand the heaviest loads on the road! The video also shows how to install MG15 Grid and a DBM layer, which are sometimes specified where heavy loading may be required.
