Freezing and thawing in the winter time will cause asphalt to crack. Most pavement that has not been sealed in a few years will have cracks that need to be treated. This is a very important step in preventing further damage to your driveway or parking lot. We use an asphalt sealing material called Dura-Fill Heat Stabilized Crack Filler which is heated to a temperature and poured into the exposed joint or crack. This is the same method used by road crews and municipalities across the country. It will last much longer than cold-apply products that you can buy at home improvement stores.
