AG has provided thousands of clients throughout the southwestern United States solutions to simple and complex engineering problems.

Our DSA, CalTrans and ACI certified lab and technicians aid our investigation and design teams by providing quality field and lab data. Our construction relates services are utilized by school districts, custom and tract home developers, cities/counties, and HOA’s. We are successful in teaming with our clients to eliminate design failures and reduce liability by leveraging our 29 years of forensic engineering expertise.


"One of the pleasures in working with American Geotechnical is their customer service. Prior to working with AG we worked with three other geotechnical engineers and none come close to AG in service and the reports are clear, concise, and understandable. We have never had a construction delay. The AG staff has ensured our jobs run smoothly with their excellent field and office staff. I truly can not say enough about the superb quality of work."
