Geoforensics is after the fact evaluation of issues and occurrences that involve the ground such as landslides, earthquakes, and natural hazards and disasters. Our experts know what they are talking about as they work around design and construction on a regular, hands-on basis. We have an exceptionally broad base of both experience and understanding and are experts in many fields including soil, water, moisture, vapor, chemical fate, concrete, corrosion, soil moisture and groundwater, and drainage. This understanding is enhanced and tempered by strong practical experiences with nearly all aspects of grading, development, foundations, and their behavior. We are not merely "professional experts”. Rather, the majority of our daily work is practical hands-on design and development. We thrive in spaces that most experts find uncomfortable.


We are experienced in various legal proceedings including mediation, arbitration, depositions, trials, expert forums, and public presentations. President of G3SoilWorks, Larry Fanning, has served as a Judicial Reference in complex CD cases, a Subject Matter Expert to the Board of Registration for Engineers and Geologists, and was appointed and served as a board member to the California State Mining and Geology Board. Other members of our senior staff have similar levels of experience and expertise with regard to forensics and expert witness services.
