Tarmac is generally considered to be the cheapest method of laying a hard surface. But it’s a time-consuming job which requires specialist tools, machinery and, not least, knowledge. This means that it only becomes the cheapest method once the driveway is up to a suitable size, where the economies of scale kick in. Once laid Tarmac driveways can look very pretty and can last you years with less maintain. The most popular standard colours are black or red tarmac but there are also other colours available too.
