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
Open-graded permeable sub-base, often Type 3 or 4/20 stone
Overflow to a soakaway or border on slow-draining ground
Edge restraint that does not block the flow

Rules in the West Midlands

In England, a new hard surface over 5 m² in front of a house needs planning permission unless it is porous or drains to a lawn, border or soakaway within the property. Any new or widened crossing over the pavement needs approval from the highway authority (the county or unitary council).
