Bowing Basement Wall Repair in Des Moines, IA
A basement wall that leans inward is one of the most common foundation problems in Iowa. Wet clay soil gets heavy, freezes and expands each winter, and over the years it can push a block wall out of line.
Request a foundation inspectionHow to spot it
A long horizontal crack about halfway up a block wall, stair-step cracks at the corners and a wall that looks curved when you sight along it are the classic signs.
Why it happens here
Saturated soil, frost pressure and downspouts dumping water next to the house all add load against the wall. Block walls are more prone to bowing than poured walls.
Measuring movement
Contractors measure how far the wall has moved from plumb. That number decides whether bracing is enough or the wall needs more work.
Steel beams
Vertical steel beams anchored to the floor and the joists above stop a wall from moving further and are a common fix for moderate bowing.
Wall anchors
Anchors set in the soil outside and tied to plates inside the basement hold the wall and can be tightened gradually over time.
Carbon fiber
Carbon fiber straps bonded to the wall add strength with little lost space, for walls that have moved only slightly.
Severe movement
Walls that have moved a lot may need excavation, straightening or partial rebuilding. That is bigger work and worth an engineer's opinion.
Reduce the load
Extending downspouts and regrading soil away from the wall lowers the pressure that caused the bowing in the first place.
