Calhoun County, TX Shrink-Swell Risk

What Calhoun County, TX's soil means for a foundation

High

USDA's SSURGO data puts Calhoun County, TX's soil at "High" shrink-swell potential, an area-weighted linear extensibility of 6.08% across 35.6% of the county's surveyed land. Soil at this level can crack a standard foundation without moisture-control measures - consistent watering near the foundation, correct grading, root barriers - or added structural design.

This is a county figure, not a lot figure

USDA's survey covers the whole of Calhoun County, TX 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 Calhoun County will actually do.

Report cost vs. repair cost

Given Calhoun County's rating, spending a few thousand now is the way to avoid spending tens of thousands later. The report ($1,000-$5,000) is what tells you whether Calhoun County's county-level reading applies to your lot; the repair ($5,000-$15,000) is what it costs if you skip that and find out from the cracks instead.
