Alligator cracking is a term referred to cracking in asphalt that looks like alligator scales. Alligator cracking can be caused by a number of things, but the most common cause is not repairing the asphalt when damages occur. When small cracks get left untreated, they allow moisture to seep into the asphalt and erode the foundation. The best solution to alligator cracking is to remove the damaged asphalt, rebuild the foundation and install new asphalt.
