Rock Mechanics
Copyright 2015 - Advanced Terra Testing, Inc.
Advanced Terra Testing's Rock Mechanics division is responsible for performing a wide range of tests under varying conditions and test parameters.

Since its inception, ATT has performed Rock Mechanics testing for hundreds of world-wide clients, ranging from North Sea oil wells, to rock fill dams in Peru, to coal mines in Colorado, to dams in Virginia, to landslides in Utah and Wyoming, to gold mining projects in the former Soviet Union, Australia, and Venezuela, and diamond mines in Canada. Our client base includes numerous civil, environmental, and mining engineering companies based both domestically and internationally.

We also have completed projects both directly and indirectly for several local, state, national, and international government agencies, such as the Wyoming Department of Transportation, the US Army Corps of Engineers, the US Department of Energy, and the Egyptian Department of Antiquities.
