Warren County, IN Shrink-Swell Risk

What Warren County, IN's soil means for a foundation

Moderate

USDA's SSURGO data puts Warren County, IN's soil at "Moderate" shrink-swell potential, an area-weighted linear extensibility of 3.53% across 81.6% of the county's surveyed land. A real but modest amount of movement - standard foundations usually hold up, but drainage and moisture control around the foundation still matter more than on low-risk soil.

This is a county figure, not a lot figure

USDA's survey covers the whole of Warren County, IN at once, not any single address. A local geotechnical report, typically $1,000-$5,000 (around $2,700 typical), is the only way to know what one lot in Warren County will actually do.

Report cost vs. repair cost

With Warren County, IN rating "Moderate", 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.
