Seal coating plays a significant part in extending the lifespan of asphalt surfaces. Asphalt protects automobiles and drivers, but seal coating preserves asphalt for as long as possible. Asphalt is a porous paving material, which makes it susceptible to damage from the elements. Seal coating can prevent water intrusion by filling cracks in the asphalt with very fine aggregate. In addition to that, seal coating prevents deterioration, improves flexibility and skid-resistance, and even enables easier cleaning of the asphalt. When you add up all these benefits, it's easy to see why seal coating is so effective at extending the life of your asphalt surfaces.
