Why Seal Coating?

Petroleum products are murder on asphalt. Oil leaks from automobiles will soften asphalt shortening its life cycle. Cotaing the asphalt with a sealant helps to fill the porous areas of the asphalt, which makes it resistant to petroleum products and other damaging elements.

Because it is more resistant to liquids, sealing the pavement also provides a barrier to natures elements. It extends the life of the pavement by sealing off cracks that rain would otherwise travel through. Eventually, and much quicker than many believe, erosion from rain causes the cracks to become larger and larger leading to failure of the pavement. In addition, sealing also helps slow down the process of oxidation. Oxygen causes the asphalt to become brittle and break away easier. It also helps to make the surface of the asphalt much more uniform.

Slows oxidation and water penetration. Exposure to oxygen hardens asphalt bingers and results in a brittle pavement surface that soon cracks. These cracks permit water to penetrate into the sub base, weakening it and reducing pavement strength. This in turn leads to more cracks, which can eventually expand and become potholes. Seal coats fill surface voids, reducing exposure to oxygen and water and prolonging pavement life.

Another harmful element of nature is the utraviolet rays from the sun that break down the carbonic bonding nature of asphalt. Sealing the pavement helps to fend off the effects of the suns rays.

Although less expensive than concrete paving, asphalt paving is still a major expense. Maintaining regular sealings of the paved area will protect your investment, and make the need for repaving every few years much less likely. Furthermore, regular sealing will maintain the appearance of the asphalt, refreshing its newly laid appearance.
