Tate County, MS Shrink-Swell Risk

What Tate County, MS's soil means for a foundation

Low

USDA's SSURGO data puts Tate County, MS's soil at "Low" shrink-swell potential, an area-weighted linear extensibility of 1.81% across 97.5% 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 Tate County, MS 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 Tate County.

Report cost vs. repair cost
