Seal-coating is one of the most important elements of a pavement plan. A seal-coat consists of either coal tar pitch or asphalt cement mixed with inert fillers, water, emulsifying agents, or additives. Applied in thin coats, pavement sealing is used to protect off-highway pavement surfaces against gasoline, oil, salt, water, and ultraviolet rays.

When covered with a dark black sealant, pavement looks and wears like new. Parking lot sealcoating helps to project a positive image of the company, facility, or residential complex.

Sealcoats fills surface voids while coating the pavement surface. The resulting smooth and even texture makes the surface easier to maintain year-round.

Sealing is not a substitute for repairs to damaged surfaces. It can, however, prolong the life of a weathered surface, and prevent good surfaces from becoming damaged. Sealcoating preserves asphalt for pennies per square foot.
