Moonsoon season has arrived in Tucson and is harsh on an asphalt driveway. Seal Coating is a protective measure taken to increase the longevity of an asphalt driveway. Sealing every 2-3 years will prolong the life of an asphalt driveway. Asphalt driveways are made up of stone, sand and asphalt cement. New asphalt looks jet black but fades over time due to the harsh weather conditions in Arizona. After time the asphalt becomes brittle and less resistant to weight placed on it. A good quality sealing will protect the asphalt from the damaging Moonsoons and prolong the life of an asphalt driveway. It will also increase the curb appeal of your driveway.
