Generated explanation

Three cross sections illustrate different patterns of inward foundation wall movement beside exterior soil backfill. The first shows a horizontal crack near midheight, with the wall bending inward at the crack. The second shows shearing near the bottom, with the upper wall displaced inward relative to its base. The third shows the top of the wall moving inward after loss of lateral support at the framing connection. Arrows indicate inward loading or movement, and each section includes framing above, a footing below, and a drain pipe beside the footing.
