Moderate risk About 10% of Dickens County's soil area is high shrink-swell (expansive) clay — far below the Texas average of 32%, and below the national average of 17%. That places it #166 of 206 Texas counties for foundation soil risk.

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. Dickens County's exposure is moderate. At 10% high-expansive soil, Dickens County carries real but uneven risk — trouble concentrates on lots with poor drainage, cut-and-fill grading, or aging plumbing leaks rather than striking every home. A soil-aware inspection beats assuming the worst.
Dickens County's shrink-swell risk is concentrated in the Pullman soil series alongside Abilene and Randall — clays the USDA maps as strongly expansive, swelling and shrinking with every wet–dry cycle. Homes built on these series most need the drainage and moisture discipline above; a lot-level soil report (or the county NRCS survey) shows which one sits under a given address.
| County | High-risk soil | |

For context, the average Texas county is 32% high-expansive soil and the average U.S. county is 17%.

The right fix depends on the actual cause of movement, so get a diagnosis before committing to clay-specific work. 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.
