Tar and chip surfacing can also rejuvenate old tarmac and concrete driveways with out the need to excavate the old surface.
Old tired broken surfaces can then be hidden beneath the tar and chippings saving the cost of removing and disposing of the old surface.
How is tar and chip surfacing carried out?
The surface is initially swept clean before all adjacent areas including kerbs and brickwork etc are masked using pvc tape to avoid spray drift. Then the surface is sprayed with hot bitumen binder before a layer of chippings typically 6-14 mm in size are rolled into the binder. On completion all tape is removed and the site left clean and tidy.
