Hill County, TX Shrink-Swell Risk

Hill County's SSURGO shrink-swell reading

High

In Hill County, TX, 45.7% of the surveyed soil carries a "High" shrink-swell rating, 7.75% linear extensibility on average. 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.

Before you rely on this for one address

Hill County's reading is an average across the whole county, not a promise about any one lot inside it. A local geotechnical report, typically $1,000-$5,000 (around $2,700 typical), is the only way to know what one lot in Hill County will actually do.

Budgeting for Hill County, TX

Given Hill County's rating, spending a few thousand now is the way to avoid spending tens of thousands later. A geotechnical report runs $1,000-$5,000 (typically $2,700); an actual foundation repair, once cracking sets in, typically runs $5,000-$15,000 (around $10,000 typical) - roughly 4x the report.
