J R Associates is a family-run business founded in 1987 to meet a need for information on what is underground using non-invasive techniques. J R Associates is a pioneering firm in civil and environmental geophysics. Performing near surface geophysical surveys for geologists and providing as-built information and drawings of buried utilities for surveyors is our business. Using a combination of experienced personnel, modern equipment and state of the art geophysical techniques, we provide accurate and cost effective subsurface information. We have successfully worked with many major utility providers including Pacific Gas and Electric, Duke Energy, the East Bay Municipal Utility District, and the Santa Clara Valley Water District as well as numerous engineering and geotechnical firms. Our subsurface information has been credited with keeping costs down on many major construction projects. Client satisfaction is our highest priority and we are proud of our record of repeat business.
