What is included?

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.

Ground check: how fast does the soil drain?
Dig out deeper than a standard drive to fit the storage layer
Geotextile separating layer on the formation
Porous asphalt binder and surface courses
Overflow to a soakaway or border on slow-draining ground
Edge restraint that does not block the flow

Rules in Argyll and Bute

In Scotland, a hard surface between the house and a road is permitted development only if it is porous or drains to a porous area within the property, whatever its size. A vehicle crossing over the footway is a separate approval, from the council as roads authority.
