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.

Survey of the existing base: sinking, rutting, loose edges and drainage
Cut out and patch failed areas before overlaying
Plane or cut back at thresholds, kerbs and covers so levels still work
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 Gwynedd

In Wales, new front hardstanding should be porous or drain to a permeable area within the property, and work covering 100 m² or more with drainage effects usually needs SAB approval first. A vehicle crossing over the footway is a separate approval, from the council as highway authority.
