Add your answer. How long does it take for cement/concrete to dry? I had a slab leak in my kitchen. A plumber came to my home and had to jack hammer a hole in the floor to get to the leak, after the repair was made he covered up the hole with cement/concrete. How long before we can actually walk on the area? I'm afraid to walk on the area if it is not strong enough, should we wait for 28 days?
