Henry County, GA Shrink-Swell Risk

What Henry County, GA's soil means for a foundation

Low

USDA's SSURGO data puts Henry County, GA's soil at "Low" shrink-swell potential, an area-weighted linear extensibility of 1.5% across 100% 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 Henry County, GA 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 Henry County, GA 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.
