That will all depend on the size and complexity of your project. However, typical concrete projects for residential use normally take 3-5 days of actual work. This will vary if we need to remove old concrete, install new base and reinforcements, and more. Curing time adds to the time required before new concrete can be used. While you will be able to walk on your new concrete after just a couple of days, it will not develop its full strength until some time has passed. It is recommended that cars and other vehicles should stay off new concrete for two weeks.
