Placing Joints in Concrete Driveways—Choose Wisely

Joints should be at least 1/4 the concrete thickness so a 1" deep joint should be used in a 4" thick driveway. Joints should also be spaced 2-3 times in feet the thickness of the concrete: so a 4" thick driveway should have joints no farther than 8' - 12'.

If joints are spaced too far apart, cracks will often occur where the joints should have been.
