What is included?

A new tarmac driveway is built from the ground up: the old surface and soil are dug out, a compacted stone sub-base is laid, then a hot binder course and a finer surface course are spread and rolled, and the edges are held by kerbs or blocks.

Geotextile membrane where the ground is soft or clay

Rules in West Glamorgan

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.
