Chip-seal

First coat chip seal is a very cost-effective option that will provide customers with a course surface that not only performs well but looks great too. Typically, we offer a two-coat chip seal option as a pavement treatment. This combines a total of two layers of emulsion with a larger sized chip on the first layer and a smaller chip on the second. The smaller chip locks into the larger chip to provide a sound running course on the constructed pavement.

Another option for an old or failing chip seal or asphalt pavement, is a reseal. This uses the same materials as a first coat chip seal, but the construction method is different. The existing pavement is swept prior to failures either being dugout and reconstructed or simply using asphalt to patch any potholes or low areas. Once again, this is a cost-effective option to rejuvenate the existing pavement surface.
