Properly constructed and maintained asphalt can last 20 to 30 years. Heavy traffic, oil and gas spills, sub base failure, water damage, droughts, heavy rains, expansion and contraction all conspire to erode and break up your parking surfaces. Sealcoating can double your asphalt’s lifespan. Repairing your asphalt and concrete is not only important for safety and fire code purposes, it also enhances your property value and the impression you make on customers.
