SEALCOAT Sealcoat is one of the most vital tools in your pavement management toolbox. Because asphalt is a flexible pavement, its performance and longevity depend on remaining flexible. Applying sealcoat increases asphalt’s ability to shed water, protects it from oxidation due to UV rays, as well as retaining flexibility. Additionally, it gives weathered asphalt a deep, like new appearance which adds to the curb-appeal and value of any property. If your paving has not been sealed in the last 3-4 years, call us soon.
