San Saba County, TX Shrink-Swell Risk

What San Saba County, TX's soil means for a foundation

Moderate

USDA's SSURGO data puts San Saba County, TX's soil at "Moderate" shrink-swell potential, an area-weighted linear extensibility of 5.17% across 42.7% 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 San Saba County, TX 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
