Tar spraying, where liquid bitumen is evenly applied to the surface of the road, driveway or path, is the first step in surface dressing. The tar seals the surface and prevents water from being able to enter which can cause serious damage to the installation.
Once the tar has been sprayed, your choice of chippings can then be applied. Chippings provide an attractive finish to tarmac surfaces and also confer anti-skid properties to that surface. Choices include granite chips, aggregate or golden gravel.
