Homeowner in New Harmony, IN was experiencing stair-step cracking throughout his basement wall. There are a number of potential causes of cracked and bowing foundation walls, but the main issue is the pressure from foundation soils.

Foundation wall anchors extend out to the stable, hard-packed soil beyond your home, anchoring themselves there and bracing the foundation wall.
