Many municipalities require soil studies prior to residential construction of footings to determine if the site has soil with volume change potential. Over the past 18 years we have performed studies on thousands of sites with potential shrink-swell soils. These studies require test borings where we collect soil samples and perform bearing tests to evaluate foundation support available. Recovered soil samples are returned to our laboratory for physical and engineering properties. The results of our testing are summarized in a report that presents foundation recommendations and a footing detail that is required by the Building Official. We can perform individual single family homes or large subdivision studies for commercial developers.
