Cracksealing is the placement of materials into non-working or low movement cracks to reduce the infiltration of water and other materials into the cracks. When done properly, cracksealing can extended the life of your pavement. By sealing cracks in your pavement you prevent water from entering, sand and rocks from making their way to the surface, minimize crack growth, and help stop new cracks from forming. Treating the problem areas while they are small is the key to proper crack filling. Crack filling pays for itself by delaying expensive asphalt resurfacing.
