Seal Coating


The sun’s ultraviolet rays harden and dry out asphalt pavements. This leads to the acceleration of raveling and erosion. Once this process starts it can reduce the thickness of your asphalt in just a few short years. Seal coating combined with a regular maintenance program will greatly reduce the speed of this natural process. Sealcoat can also protect your asphalt from the effects of harsh chemicals.


Use sealcoat to increase surface friction and keep your pavement from becoming slippery, which can lead to an increase in accidents. Properly sealed cracks combined with seal coating prevent the damaging effects of water penetration that occur over time. When seal coating is a part of a regular maintenance routine that includes asphalt crack repair, it is the most effective way to prevent water infiltration and eliminate many costly repairs throughout the life of your asphalt. Regular seal coating restores the asphalts’ rich black finish. Contrasted with freshly striped parking lot lines it also provides a safe and orderly business environment. The smooth even surface of sealed pavement makes maintenance, snow removal and sweeping less costly.


Sealcoat costs pennies per square foot to apply. Compare that to the many dollars needed to repair or replace damaged asphalt and the advantage is clear.


A fresh sealcoat application results in a rich black finish. The result is a great first impression for customers, residents, and homeowners.

Our Process

We visit your site to confirm the suitability of sealcoat for your pavement. Once you accept our estimate, we get to work. A mixture of emulsified coal tar, water, mineral fillers, sand and various other components are combined to create the sealcoat. Our premium grade sealcoat includes select, highly stable polymer binder additives with cross-linking chemistry and fine-graded sand for traction and wearing surface.

Mechanical spray, rubber squeegee, or broom is used to apply the sealcoat. Many pavement engineers recommend a two-coat application using a squeegee application on the first coat and a spray application on the second. This allows the mechanical down pressure of a squeegee to fill cracks, displace dust particles and to insure adherence while the second spray coat provides an even filling of voids and a smooth, uniform finish.
