All tarmac are done to the same spec as the bloc paving. Dug out and stoned up to a thickness of 4 – 8 inches depending on the ground underneath, with type 1 hardcore and compacted with a roller. The tarmac is layed in two layers, the base course will be around 50mm thick when rolled and the top course will be around 25mm thick when rolled. Our customers have a choice of red or black, quality top coats.
