When cracks form they immediately begin allowing water into the base and sub-base of the asphalt. This causes asphalt to deteriorate and become unstable allowing cracks to spread resulting in potholes and need for extensive repairs.
Repairing pavement cracks with a hot rubberized crack sealant will extend the life expectancy of your pavement surface by up to 50 percent at a cost far less then asphalt patching or reconstruction. Crack sealing used as an annual preventative maintenance program will add value to your investment for years to come.
