What Causes Step Cracks?

Step cracks normally form in corners near basement windows. They are caused by simple concrete shrinkage and typically form in pairs. They can also occur under a home’s center I-Beam, which is common. All step cracks are of little concern, except when found in combination with horizontal cracks. If the step crack is moving, or wider at the bottom than at the top, it can be an indication of settlement.
