Maury County, TN Shrink-Swell Risk

What Maury County, TN's soil means for a foundation

Low

USDA's SSURGO data puts Maury County, TN's soil at "Low" shrink-swell potential, an area-weighted linear extensibility of 2.65% across 62.1% 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 Maury County, TN 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 Maury County will actually do.

Report cost vs. repair cost

With Maury County, TN 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.
