Herndon Asphalt can provide a complete consultation on the condition of your existing pavement and which maintenance repairs are needed to prolong your asphalt surface.  We use SCDOT appoved hot-mix patching for potholes, after a complete cleaning and prepping of the asphalt surface.

Why Crack Fill?

Crack filling your asphalt driveway or parking lot surface is a very important part of extending the life of your asphalt surface. The two most important reasons you need to maintain and repair the cracks is because you don’t want moisture to penetrate under the asphalt surface causing more damage to your driveway or parking lot. The second reason is because vegetation will begin growing in the cracks. As the roots on vegetation get bigger, the plant root can actually push the pavement up and create even more damage. This breaks the pavement surface and other problems begin occurring.

Even worse, if water does penetrate the crack and seeps under the asphalt surface, this will almost always creates a soft spot which can create a Pot Hole. When the ground freezes during winter, the moisture in the asphalt surface widens the cracks. All of these conditions can usually be avoided by practicing good maintenance and keeping these cracks filled as they occur. On the other hand, if you have areas in your pavement that looks like alligator skin (alligator cracks), this is is characterized by many cracks  in one area and is a complete failure of your existing asphalt surface. You likely will need to patch the entire area.
