Filling cracks in your asphalt driveway or parking lot surface is a very important part of extending the life of the asphalt surface. This prevents moisture from penetrating the surface, and keeps vegetation from growing in the cracks.
Prevent Moisture Damage
Crack Filling is used to prevent moisture from penetrating under the asphalt surface, causing damage to the driveway or parking lot. Of course you should sealcoat your asphalt surface as well, for added protection and preventive maintenance.
Stop Vegetation growing
As the roots of vegetation get bigger, the plant root can actually push the pavement up and create even more damage. Even worse, if water does penetrate the crack and seep under the asphalt surface, this will almost always create a soft spot which, in turn, can create a pothole or depression.
