Earth Dynamics has provided professional services to government and public industries since 1984.  Prior to 1996, the firm operated under the name of its founder, Dr. Michael Feves.  The firm has earned a reputation for using innovative approaches to complete challenging projects on time and within budget.

Requirements for individual projects vary widely.  Dr. Feves and his staff know the capabilities of each technique and type of equipment.  Each project is tailored to the specific site conditions and data requirements of the client to provide the best information for the lowest cost.

Earth Dynamics specializes in a wide variety of non-invasive geophysical methods that can be used to determine depth to bedrock, determine subsurface soil and rock conditions, and locate buried objects such as utilities, drums, and voids.  The lists below have links to pages with descriptions and applications of each method.
