Montgomery County, IN Shrink-Swell Risk

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

Moderate

USDA's SSURGO data puts Montgomery County, IN's soil at "Moderate" shrink-swell potential, an area-weighted linear extensibility of 3.5% across 80.9% 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 Montgomery County, IN at once, not any single address. The real answer for one lot is still a site-specific geotechnical report, running about $1,000-$5,000 (typically near $2,700).

Report cost vs. repair cost

With Montgomery 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.
