It is recommended that an asphalt parking lot be maintained regularly to prevent the surface from deteriorating, to slow the formation of stress cracks, and also to maintain the aesthetics of your property. We recommend annual preventative maintenance such as crack-filling when new cracks occur. Sealer should be applied to your lot approx. every two years depending on the traffic and wear that you see. Corrective maintenance is necessary when excessive cracking occurs or other structurally failed areas develop. This type of maintenance includes pothole filling, asphalt removal and replacement (localized patching), overlay/resurface, or a complete removal and replacement.
