About

A Temecula practice, working California ground since 2007.

Earth-Strata Geotechnical Services, Inc. is a geotechnical, environmental, and materials testing consulting practice. We test and interpret the engineering properties of the earth’s strata to aid the design and construction of structures — from project conception through completion.

The office is in Temecula. Work is typically throughout Riverside County and the rest of California: residential tracts, commercial pads, public works, and due-diligence studies.
