Joints or cracks in pavement, whether it is an asphalt parking lot, driveway or road, that are not properly crack sealed can cause premature deterioration of the surface. THE MAIN PURPOSE OF CRACK SEALING IN ASPHALT OR CONCRETE IS TO PROTECT YOUR PAVEMENT FROM PREMATURE FAILURE.
Unsealed cracks allow water and debris to flow into the crack opening. Water will create a weakened base, sub-base and surface resulting in alligator cracking and load related failures. Debris can cause the edges of the cracks to push up due to expansion from thermal changes.
Routine crack sealing maintenance not only makes your asphalt surface look good, it:
-Saves you money by extending the life of your asphalt. -Prevents unsightly weed growth. -Stops water from entering the base under the paved surface which leads to potholes, sinkholes and heaving from freezing
