Joints or cracks in pavement, if not sealed properly, will allow water, dirt and other foreign materials to enter. As water soaks down through the unsealed cracks, damage will occur through the freezing and thawing cycles. Allowing water to penetrate beneath the joint or crack will also displace the sub-grade, which will cause further cracking and generally deteriorate the traffic surface. Don't wait for the problem to get worse, call Pro Pavement Services Ltd. for crack sealing at your business in Southern Ontario.
