White County, IN Shrink-Swell Risk
What White County, IN's soil means for a foundation
Low
USDA's SSURGO data puts White County, IN's soil at "Low" shrink-swell potential, an area-weighted linear extensibility of 2.42% across 64.3% of the county's surveyed land. That's as favorable a county-level reading as this dataset produces - standard foundation practice, pending one lot's own geotechnical report.
This is a county figure, not a lot figure
USDA's survey covers the whole of White County, IN at once, not any single address. A site-specific soil report, usually $1,000-$5,000, is what an engineer would actually pull before designing a foundation on a lot in White County.
Report cost vs. repair cost
With White County, IN rating "Low", a geotechnical report is still worthwhile before a build, just less urgent than in a high-risk county. A geotechnical report runs $1,000-$5,000, typically around $2,700. Foundation repair, if a specific lot turns out to differ from the county average, runs $5,000-$15,000.
