How it is built

What we do on a permeable tarmac driveway

A permeable tarmac drive uses porous asphalt, a mix with fewer fine particles so water passes through the gaps, laid on an open-graded stone base that stores the rain and lets it soak into the ground.

Dig out deeper than a standard drive to fit the storage layer
Geotextile separating layer on the formation
Open-graded permeable sub-base, often Type 3 or 4/20 stone
Porous asphalt binder and surface courses
Edge restraint that does not block the flow
