Chambers County, TX Shrink-Swell Risk
Chambers County's SSURGO shrink-swell reading
High
In Chambers County, TX, 43.9% of the surveyed soil carries a "High" shrink-swell rating, 8.21% linear extensibility on average. Ground like this needs active moisture control to keep a conventional foundation from cracking - it's not automatic either way.
Before you rely on this for one address
Chambers County's reading is an average across the whole county, not a promise about any one lot inside it. The real answer for one lot is still a site-specific geotechnical report, running about $1,000-$5,000 (typically near $2,700).
Budgeting for Chambers County, TX
Given Chambers County's rating, spending a few thousand now is the way to avoid spending tens of thousands later.
