The sub-bases are laid in a 150mm-450mm thick layer under a variety of pavement offerings: paving slabs, asphalt & concrete. The 2-6mm is dual purpose as this can also be used as a brushing-in grit.

Rainfall drains through the pervious pavement and filters into the sub-base. either slowly draining into the ground below or stored in the sub-base for reuse, preventing pooling on the surface.
