Canadian County soil
- About 20% of the county is rated expansive; Norge (16%) and Bethany (7%) are the most common series, and the median home was built in 1999 (FoundationSoils, Canadian County (USDA SSURGO)).
- An OSU soil benchmark study found smectite, the clay mineral that swells most, in the subsoil of Bethany, Kirkland and Norge profiles sampled in Canadian County (OSU benchmark soils study).
Tip: A 1999-or-newer Mustang home may still have builder warranty or footing records; ask for them before paying for an evaluation.
