Sealcoating is an extremely important part of maintaining parking lot and driveway paving. Sealcoats consist of their coal tar pitch or asphalt cement mixed with inert fillers, water, emulsifying agents or additives and let’s not forget the most important part, sand. Pavement sealing is used to protect off-highway pavement surfaces against gasoline, oil, salt, water and ultraviolet rays. Seal coating provides an aesthetically pleasing black finish that protects and prolongs the life of your parking lot.
