Our Technology

We are a modern archaeological and natural resources services company demanded by today's planning and development professionals. By effectively integrating scientific research and field methods with our proprietary geophysical technologies, we are able to increase the speed and reliability of gathering field survey date, as well as reduce and eliminate work stoppages due to the inevitable "new discovery" of archaeological sites obscured by vegetation, fill, or natural deposition.

Mobile EM^3

TREMAINE's propreitary EM3 technology gives us a capability that is unique in the industry. A mobile geophysical instrument for near-surface (upper 10 meters) electromagnetic investigations. Both apparent conductivity and magnetic susceptibility data are acquired for three volumes/depths simultaneously, resulting in a tremendous increase in data, consequently greater confidence regarding subsurface conditions.


This information is useful for identifying buried cultural resources. It is also very useful within a number of decision making arenas of project development, particularly, design engineering, geotechnical, environmental, and ROW/utilities. By identifying potential problems during the planning and design phase, rather than down the road, the “unforeseen” is avoided, reducing design errors and omissions, schedule slippage, scope creep, and cost overruns. It can also be used as a fact-based audit of the project area's subsurface environment (part of a project constructability review).


Our technology has enormous potential for payoffs, given that currently, over 50% of all construction claims and change orders are the result of insufficient subsurface information.

TREMAINE uses additional geophysical methods in conjunction with the EM3 to characterize the subsurface environment as accurately as possible. These methods are generally employed subsequent to the EM3 survey to better delineate those potential cultural resources or unforeseen obstacles found with the EM3. These methods are also used where site and/or soil conditions are not conducive to obtaining good EM results, allowing TREMAINE to conduct surveys in a wide range of environments.


The complementary nature of the resistivity data allows for more accurate models of the subsurface to be generated from the EM3 data, reducing the need for more expensive subsurface testing. Ground penetrating radar is now a commonly used technique in geotechnical, engineering and ROW/utilities investigations for providing high resolution images of the buried strata and objects. The combined use of these different methods provides a powerful “toolbox” for cultural resource, environmental, geotechnical and ROW/utilities investigations.
