The preliminary work significantly impacts the time needed to install a new driveway. Most driveways may be installed within two days once the land has been prepared. Your concrete driveway needs time to set completely for it to be durable. The thickness of the slab, the foundation used, and environmental factors affect how long it takes for the concrete to be fully set. However, you can walk on your driveway after 2 days. After seven days, you can use regular vehicles on the driveway, but you should avoid using heavier ones. Your driveway should be fully set and suitable for use after 30 days.
