Sealcoating is one of the most beneficial services you can provide for your pavement. Our coal tar emulsion sealer provides a protective barrier for your asphalt. The elements then eat away at the sealer not your asphalt parking lot. This process will greatly extend the life of your pavement and restore its original beauty in the process. Your pavement needs to be sealcoating the first year after installation and every 2-3 years following depending on the amount of traffic.
