When people have a new concrete driveway installed, they are often anxious to use it as soon as possible. But before you can use a driveway, the concrete must first be cured. Curing is the term applied to the complete drying process of the concrete, that allows the concrete to reach its strongest point. There is no hard and fast rule for curing time in a concrete driveway. The curing time can vary, depending on the kind of concrete used, and the ratio of water to the concrete mixture. The best way to determine the proper curing time is to ask the concrete company that installed your driveway or read the curing time information on the packaging your concrete came in.
