Sealcoating provides a layer of protection blocking out the elements: water, oils, and U.V. damage. In addition to preventative maintenance benefits, sealcoating provides a deep black finish that beautifies the parking lot or driveway. The sealcoat is in a liquid formulation of an asphalt or coal tar emulsion, mixed with water, silica sand, polymer additives and other proprietary fillers and solids. A regularly scheduled sealcoating program can more than double the life of the asphalt, saving you significant dollars down the line. Instead of having to pay thousands of dollars for new pavement, you can spend pennies on the dollar to maintain.
