| Sealcoating is important for several
reasons. Sealcoating prevents oxidation. Asphalt
pavement begins to deteriorate almost as soon as it is placed. As the pavement is exposed
to oxygen, the asphalt binder (tar) hardens. This hardening results in a brittle surface
that eventually 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.
Sealcoating resists ultraviolet rays. By breaking down
the links between the carbon bonds in the asphalt, ultraviolet rays cause pavement to
deteriorate and crumble. Regularly applied sealcoat helps to prevent ultraviolet rays from
penetrating the pavement.
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.
Sealcoating enhances pavement appearance and eases maintenance.
Sealcoating
brings back the dark black color of the original pavement, making it look and wear
like new. Sealcoated pavement 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. |
