Foundation wall bowing inward — San Francisco, California
A foundation wall that bows inward is a structural emergency. Lateral soil and hydrostatic pressure push the wall beyond its design capacity, creating horizontal cracks at the midpoint and step cracks at corners. Left unaddressed, the wall can eventually collapse. A foundation specialist evaluates the deflection, installs carbon-fiber straps, steel I-beams, or helical tiebacks depending on severity, and addresses the drainage deficiency that caused the pressure.
