Rules that apply in Dinas Powys

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. Any new or widened crossing over the pavement needs approval from the council as highway authority.

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.

Dig to formation level, usually around 230–250 mm below finished height
Geotextile membrane where the ground is soft or clay
Concrete-haunched kerbs or a block-paved border as edge restraint
Binder course (AC 20 dense), about 50–60 mm, laid hot and rolled
Falls set so water runs to a channel, gully or soft landscaping
