Basements are common in the Kansas City area. In 2025, 64.4% of new homes in the Census region that includes Missouri and Kansas had full or partial basements. The soil outside presses on those walls, and wet or frozen clay presses harder.
Why walls bow
HUD's inspection guide says sweeping or horizontal cracking of block or brick foundation walls can come from poor backfilling, heavy vehicles near the wall, or swelling or freezing of water-soaked soil beside it. It calls this potentially serious.
Ways to fix it
- Wall anchors: a plate inside the wall is tied to an anchor set in the yard
- Tiebacks: helical piers in the yard tied to a plate on the wall
- Steel braces set against the wall inside the basement
- Carbon fiber straps bonded to the inside of the wall
Ease the pressure
HUD says to look for broken downspouts and poor surface drainage when expansive soil is suspected, and notes that lowering the ground outside can relieve some pressure on the wall. Fixr suggests pairing tiebacks with waterproofing.
Questions to ask
- How far has the wall moved, and will it be pulled back or just held?
- How many anchors, braces or straps, and how far apart?
- Is a permit needed where I live, and will you pull it?
- What does the warranty cover, and does it transfer if I sell?

Questions
Can a bowed wall be pushed back?
Sometimes. HUD notes a wall may be pushed back by careful jacking and then reinforced. Ask the company whether your wall can be straightened or should be held where it is.
Is a stair-step crack in a block wall the same problem?
Not always. HUD links horizontal cracking to soil pressure and frost, and other masonry cracking to settlement. Have a company look at both.
