Crack Sealing will prevent the deterioration of the sub-based pavement from the infiltration of water (ice/rain/snow) and debris. The thorough cleaning of the affected areas and the application of crack sealant will prevent further erosion of the surface and damage to the structural support of the pavement. Crack seal material is designed to expand and shrink allowing for year-round performance. By sealing cracks, you can extend the life of your pavement and prevent more costly repairs.
