The Earth Systems group of companies offers a variety of geophysical services to assist in imaging subsurface geology and locating buried features. While geophysics is not a substitute for borings or other methods of obtaining physical subsurface data, it is an excellent means of interpolating between borings, thus enhancing our understanding of broad subsurface areas while limiting destructive testing. At sites where access is limited, drilling is difficult, or non-invasive exploration techniques are desired, geophysical surveying can be an effective and economical tool. Our geophysical services include the following methods. (For detailed descriptions, please click the links.
