Low risk About 0% of Van Buren County's soil area is high shrink-swell (expansive) clay — far below the Michigan average of 3%, and far below the national average of 17%. That places it #78 of 79 Michigan counties for foundation soil risk.
Share of the county's ~399,296 acres of USDA-mapped soil with linear extensibility ≥ 6% in the top meter (SSURGO).

Expansive clay swells as it takes on water and shrinks as it dries, and that repeated movement is what lifts and drops a foundation unevenly — opening stair-step cracks, racking door and window frames, and, left unmanaged, cracking slabs and footings. Van Buren County's exposure is minimal. With just 0% high-expansive soil, expansive clay is unlikely to be the main driver of foundation movement in Van Buren County. Settlement here more often traces to drainage, fill, tree roots, or original construction — worth a diagnosis before paying for clay fixes.

For context, the average Michigan county is 3% high-expansive soil and the average U.S. county is 17%.

At this risk level the clay is rarely the culprit, so a proper diagnosis is the first dollar to spend. See the full foundation repair cost guide for method-by-method pricing.
Risk metrics are computed from USDA SSURGO soil survey data (linear extensibility of soil components, area-weighted by county). Soil varies lot to lot — this is county-scale context, not a substitute for a site-specific geotechnical or structural assessment.
