" The Driveway Guy"
Residential Driveways & Commercial Parking Lot Seal Coating
Why Sealcoat?
  
Asphalt driveways are made up of stones, fine sands, and asphalt binder. The binder acts as the glue to hold all of these aggregates together and provides the driveway with the rich, black color.

However, over time, the binder begins to oxidize with exposure to sun, rain, snow, and other elements – this is shown by the driveway’s color fading to gray. As the asphalt oxidizes, it becomes less flexible and cracks more easily allowing water to penetrate the driveway. Once water enters the driveway it slowly destroys it by expanding and contracting during freeze/thaw cycles. Combine this deterioration with exposure to harmful chemicals like motor oil and landscaping or household chemicals and your driveway doesn't stand a chance.

To prevent the harm caused by leaving your pavement unprotected, sealcoating is applied to “seal” out the sun's UV rays, rain, snow, and harmful chemicals. In fact, many studies have shown that maintaining pavement by sealcoating prolongs the life of your driveway and will prevent the need to repair or replace it for many years.


Sealcoating costs pennies a square foot compared to the dollars needed to repair or replace damaged asphalt.
