How Thick Should Concrete Driveways Be?

If you are pouring your own concrete driveways, you will have to determine how thick to make it. In most cases, you will want to make the driveway at least 6 inches thick. You should never go less than 4 inches when pouring a concrete driveway; otherwise, the concrete will most likely crack and break after you drive your car on it repeatedly. You need to make sure that the concrete can stand up to a lot of wear and tear, so if necessary, it is better to err on the side of 'too thick.'
