What the price covers

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.

  • Break out and remove the old surface and spoil
  • Dig to formation level, usually around 230–250 mm below finished height
  • MOT Type 1 sub-base laid and compacted in layers, about 150 mm
  • Binder course (AC 20 dense), about 50–60 mm, laid hot and rolled
  • Surface course (AC 6 dense), about 20–30 mm, laid hot and rolled
