Chip and spray

We provide chip and spray, which is a sprayed application of modified bituminous binder followed by a single layer of stone chipping, followed by a second spray application of bituminous binder and a single layer of smaller sized stone chipping or sand. If its double seal that when we put another layer of stones on top but if its single seal we usually spray fog spray 30% KRS or SS60 cationic,depending with the engineer specification ob single seal we can put a slurry seal on top of the single seal and it will become a cape seal.
The final layer of stone chipping is sometimes covered by a fog spray, which helps to prevent whip-off.

This is mainly done to provide:

  • A waterproof cover to the underlying pavement
  • A safe all-weather, dust-free riding surface for traffic with adequate skid resistance
  • Protection to the underlying layer from the abrasive and destructive forces of traffic and the environment Single Seal and Double Seal

A double seal is a sprayed application of bituminous binder followed by a single layer of stone chippings, followed by a second spray application of bituminous binder and a single layer of smaller sized stone chippings or sand. The final layer of stone chippings is sometimes covered by a fog spray to prevent whip-off. Double seals can be made up from the following combinations of stone aggregate and sand:

  • 9,5 mm chips and sand
  • 13,2 mm chips and sand
  • 13,2 mm chips and 6,7 mm

A double seal is normally used as a first seal on a newly constructed road where a more durable surfacing than a single seal is required. A double seal is applied to:

  • 2 Layer of stone chips on 1st spray
