This is the process of filling in cracks in asphalt or concrete. This also prolongs the life of your pavement. It also improves the appearance and keeps roots and plants from growing up into your pavement. Cracks allow moisture penetration from rain, snow, salt, and ice, which erodes the base of your parking lot.  As these harmful substances penetrate into the subbase of the pavement, the cracks widen and eventually cause potholes.  Unrepaired potholes will chip away and become more severe pavement issues.  This exposes you to serious liability, as potholes are trip hazards to tenants, customers, and employees.  Vegetation and other impediments to crack sealing are cleared. The cracks are then sealed using hot-applied rubberized joint sealant.
