Ground you can build on.
Earth-Strata Geotechnical Services, Inc. tests and interprets the earth beneath your project — from first boring through final compaction.
Practice
Geotechnical, geologic, and materials consulting
We are a complete consulting firm: investigations, laboratory testing, and field observation for public and private work across California.
Geotechnical investigations
Subsurface exploration, borings, and engineering analysis to support design of foundations, slopes, and earthwork.
Engineering geology
Geologic mapping and hazard assessment so grading and foundations sit on ground you actually understand.
Materials testing
Laboratory and field testing of soils, aggregate, concrete, and asphalt to verify what the plans assume.
Grading observation
On-site observation during mass grading and foundation construction so the work matches the geotechnical report.
How we work
Practical recommendations. Prompt field response.
- Clear reports written for designers, contractors, and plan checkers — not just the file.
- Field staff who show up when grading is moving, not after the lift is buried.
- One office in Temecula covering investigations, lab work, and observation.
