Why Sealcoating is important?
Sealcoating allows the asphalt to fight the elements
Element #1: Sun and Oxidation
Asphalt pavement begins to deteriorate almost as soon as it has been layed. This process of deterioration is called oxidation. As the pavement is exposed to oxygen, the asphalt binder (tar) hardens. This hardening results in the surface becoming weaker, eventually leading to cracks. Cracks in the pavement enable oxygen and rainwater to penetrate the pavement, often into the subbase, weakening it and reducing the pavement's strength. Sealcoating protects the surface and fills surface voids, reducing pavement's exposure to oxygen and water and extending pavement life.
Element #2: Water & Rain
Sealcoating can also prevent water from seeping through the surface, which can cause a softening of the base. This softening can lead to depressions in the pavement, as well as allow to crumbling and erosion to occur. Sealcoating allows the pavement service to repel and redirect water penetration.
Element #3: Oil & Gas Spills
Sealcoating resists oil and gas spills. This is especially important on driveways where cars are parked or worked on. Oil and gasoline soften asphalt. Our professional-grade sealer contains additives that enable it to resist any such leaks. By filling surface voids, sealcoating also reduces the depth to which oil or gas can penetrate the pavement.
The Result: If Sealcoated on a regular basis
Sealcoating enhances pavement appearance and lengthens the life of the pavement, which increases the overall value of the driveway or parking lot. In addition sealcoating is also easier to clean and maintain. Because sealcoat fills surface voids, a sealcoated surface is much smoother. And a smoother surface is easier to sweep, shovel, and wash.
