Wide, jagged cracks accompanied by heaving or settling may require full slab replacement. What you want to watch for are cracks that are wider than 25mm and are uneven, meaning they`re not located in a control joint but rather in the plane of the driveway. These could indicate an underlying structural problem, especially if the surface of the driveway is higher on one side of the crack than the other. While this type of problem is more common with older driveways than with newer ones, its an indication that the driveway, or at least the section with the cracks, should be replaced.
