What is Sealcoating?
Asphalt sealcoating is a liquid coating of an asphalt surface that is used to help protect asphalt. Protection is created in much the same manner as staining wood. Asphalt pavement is essentially made up of rock, oil and sand. The oil within the asphalt pavement helps hold together the rock and sand, but when the oil begins to lose its ability to bond, the asphalt pavement will begin to unravel and deteriorate.

Protect Your Parking Lot or Driveway

Beautify
Restore the original “black” rich look of new pavement. Sealcoating beautifies and enhances your landscaping, (change to property) thereby increasing the value of your property. Sealcoat keeps your property looking like new while protecting it.

Prevent oxidation
Block out the damaging effects of the sun and ultraviolet rays.

Spill damage
Keep spills – gasoline, oil or any other chemicals - from penetrating the surface of your asphalt.

Weatherproof
Protect against the number one pavement destroyer, weather! Water can get into the base layer and cause movement, which leads to cracks, aligatoring and damage from freeze and thaw cycles.

Maintenance
Shield your pavement against the elements that cause cracks and pot holes. Make your property safer, cleaner and more attractive.
