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
- Open-graded permeable sub-base, often Type 3 or 4/20 stone
- 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 the Forth Valley
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. If the job needs a dropped kerb, the council as roads authority approves it before any work on the footway.
