What is included in 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
- Overflow to a soakaway or border on slow-draining ground
Do I need permission in Llantrisant?
In Wales, a new hard surface in front of a house is permitted development only if it is porous or drains to a permeable area within the property; repairing or replacing up to 5 m² of existing hardstanding is allowed without meeting that condition. Separately, since January 2019, construction covering 100 m² or more that affects drainage generally needs approval from the council's SuDS Approving Body (SAB) before work starts, even where planning permission is not needed. Larger drives, shared surfaces and car parks often reach that threshold. A vehicle crossing over the footway is a separate approval, from the council as highway authority.
