Why Geophysics?

Because regarless of the possible application — engineering, environmental, or archeological — high resolution geophysical methods offer non-invasive methods to help “see what you’ve been missing” in the subsurface. A client calls and needs to find voids under an airport runway ASAP. Or your firm needs to delineate the boundaries of a contaminant plume that is thought to be flowing from a landfill. Or you need to know how deep the bedrock is for your foundation design. In situations like these, the job needs to be done quickly and efficiently. That’s the benefit of geophysics. Geophysical surveys can provide accurate and timely answers to questions with a minimum amount of disturbance to the surface of a site. In essence, geophysics allows you to “see below the surface” without having to excavate large areas or drill an inordinate number of boreholes.

Hager-Richter's work has included geophysical surveys for the seismic design of wind farms.

Why Hager-Richter?

The solution is simple. The right tools in the right hands are what you need for your project's success.

More than two decades of experience have allowed us to develop a keen sense of which survey methods will be most beneficial for a given situation. We try to overcome site-specific limitations and provide an accurate interpretation of the data.

State-of-the-art equipment complements our experience. Since we continually upgrade our equipment, our clients can be assured of the accuracy and dependability of the data collected.

We enjoy the reputation as being, "the specialists that specialists come to." Knowledgeable, sophisticated and smart clients come to us to bring our expertise into their investigations. However, don't take our word for it. The following testimony represents just a small sample of the positive word of mouth our work generates:

"It's praise well-deserved, as I tell folks here. I will only use H-R for the geophysica l surveys on my projects. Your work is FAR superior to your competitors and the responsiveness, precision, accuracy and reporting is truly astounding. You guys are my "X-Ray vision" out there. You make our jobs easier. My sincere thanks to you and the team!"

"Thank all your help and for the valuable service your company always provides to us. We were able to meet our client's needs, and get the job done on time."

"In general, I can not see a reason to work with any other geophysical company — you have exceeded expectations."

"As always, Hager Richter presents a quality product which always addresses the client's needs and usually contains more that what the client asked for."
