Why Seal Coat Your Driveway?

Seal Coating prevents oxidation. Asphalt pavement begins to deteriorate almost as soon as it is paved. As the pavement is exposed to oxygen, the asphalt binder (tar) hardens. This hardening results in a brittle surface that eventually cracks. Cracks in the pavement enable oxygen and rainwater to penetrate the pavement, often into the sub base, weakening it and reducing the pavement’s strength.

Seal Coating protects the surface and fills surface voids, reducing pavement’s exposure to oxygen and water and extending pavement life. It will also enhance the appearance of the pavement, reduce maintenance and brings back the dark black color of the original pavement, making it look and wear like new. Because seal coat fills surface voids, a seal coated surface is much smoother, which is easier to sweep, shovel, and wash.
