Understanding the Ways That Sealcoating Can Benefit Your Asphalt Surface

by | Sep 5, 2019 | Construction & Contractors

Asphalt makes a great material to form driveways, parking lots, and other hard-surface areas. Over time, however, asphalt can break down as it is exposed to the elements. To help protect your asphalt surfaces, sealcoating in Manchester, NH, can go a long way to seal, protect, and prolong the life of your driveway or parking lot. Here are a few benefits of sealcoating your asphalt surfaces.


Since asphalt is ultimately a porous material, it is susceptible to wear and tear from water, sun, and varying temperatures, over time. Without sealcoating in Manchester, NH, an asphalt surface will eventually develop cracks and potholes that can be inconvenient or even dangerous to drive and walk on. Sealcoating protects the surface of the asphalt with a non-porous barrier that greatly reduces the amount of moisture that’s able to find its way into the asphalt. This, in turn, reduces the stress that temperature differences place on the asphalt, helping to prevent cracks and potholes.


Although sealcoating provides an excellent surface barrier for asphalt, it also does a great job of filling in cracks and holes that may already have formed in the asphalt. This process is important to restore a smooth and impenetrable surface that can withstand the elements. Since the sealcoating substance remains flexible after it dries, the gaps that it fills typically don’t grow larger, even as the temperature continues to change throughout the year.

Looks Great

One of the most noticeable characteristics of aging asphalt is its change in appearance. Instead of a smooth, black surface, you end up with a rough, light gray surface that looks dated and worn. Sealcoating, though, can instantly transform the appearance of your aged asphalt, restoring it to its original color and texture at a lower cost than having the surface repaved. Whether you’re sealcoating a parking lot at your business or a driveway at your home, this improved appearance will help make the rest of your property look better, as well.
