Why do walls bow?
Most Wisconsin homes have basement walls below grade. Over time the settling of ground, clay swelling, the plugging of drain tile, extensive rains, and plumbing leaks can cause a basement wall to bow, tilt inwards, and crack. To repair a bowed wall the first step to this process is to eliminate the problem by excavating and removing the earth pressure against the wall. In most cases this highly expansive clay is the main cause of the foundation bowing.
