Layer by layer

What is included in a new tarmac driveway?

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
Geotextile membrane where the ground is soft or clay
MOT Type 1 sub-base laid and compacted in layers, about 150 mm
Concrete-haunched kerbs or a block-paved border as edge restraint
Falls set so water runs to a channel, gully or soft landscaping
