Coal tar Sealer has a great advantage over asphalt Sealer in that Coal tar coatings hold up better under exposures of petroleum oils and inorganic acids. Another outstanding quality of Coal Tar Coatings is their extremely low permeability to moisture and there high dielectric resistance, both of which contribute to the corrosion resistance. Make sure you ask your driveway sealing Company what sealer they use the alternative is asphalt sealer which is thinner and will not protect your driveway from gas or oil leaks.
Asphalt pavement is a mixture of graded stone aggregate and asphalt. The asphalt is the binder or glue that holds the pavement together. If left unprotected, asphalt is subject to degradation from oxidation and water penetration. Ultraviolet rays from the sun begin to break down the asphalt binder, changing the pavement surface color from black to gray. Gas, oil and other petrochemicals will dissolve the asphalt binder, causing holes and raveling. If cracks are present in your driveway or parking lot, water will begin to erode the base beneath the asphalt, causing the cracks to enlarge and eventually causing base failure.
