What is included?

Tarmac resurfacing, or an overlay, means cleaning and repairing an existing drive, spraying a bond coat and laying a new surface course of about 25–40 mm on top, without digging out the base.

Cut out and patch failed areas before overlaying
Plane or cut back at thresholds, kerbs and covers so levels still work
Weed treatment and a clean surface
Bond (tack) coat sprayed to glue the new layer to the old
New surface course, typically 25–40 mm, laid hot and rolled
Edges sealed and joints to existing surfaces cut neatly

Rules in South Glamorgan

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.
