WHY IS IT IMPORTANT TO FILL CRACKS?
Crack filling is used as a first defense against pavement deterioration because it offers several important benefits. Effective crack sealing keeps water from entering and weakening the base or sub-base. It helps preserve the pavement adjacent to the cracks; prevents sand, stone, and dirt from making its way into open cracks causing compressive stresses and extends pavement life by minimizing crack growth. Proper attention to cracks will prevent problems from spreading and double the life of the pavement. Pavement repair in the early stages of deterioration will pay big dividends later by delaying costly resurfacing.
