The installation of your parking lot or driveway was a big investment, and without regular maintenance you can expect pricey repairs within 7-12 years. Because of its vulnerability to UV radiation and chemicals such as melting salts and automotive fluids, it is essential to properly sealcoat asphalt in order to protect your investment and avoid costly replacement.
Crack sealing is a method of maintenance done in addition to sealcoating or on its own. If cracks are left unattended, water can penetrate to the asphalt base and drastically weaken your parking lot or driveway. This type of damage is evidenced by "alligator" cracking, sunken areas, and eventually potholes.
Like any investment, upkeep is important and ultimately less costly than a total replacement. Sealcoating and crack sealing can double and often triple the life of your pavement and save you thousands of dollars. For example, if you own a 3000 square yard paved lot, scheduled maintenance would save you approximately $45,000 over 15 years or about $3000 per year.
