Local Soil Factors

Much of the Oklahoma City metro sits on clay soils that swell when wet and shrink when dry. Long, hot summers followed by heavy spring rain can lift and drop parts of a foundation unevenly.^[2] USDA soil survey data puts shrink-swell clay that limits slab homes on about 20.8% of Oklahoma County's mapped land. The same county was 100% in drought on the September 29, 2026 U.S. Drought Monitor map.^[5] That said, the dominant NRCS shrink-swell class for Oklahoma County as a whole is rated "Low", with about 26% of land rated High or Very High.^[6] So problems vary lot by lot, which is why an on-site inspection matters.
