Rock Mechanics, Rock Testing & Materials Mechanical Characterization

We are expertes in advanced modeling and design of surface and underground mines, dams, and tunnels. Our espertise allow us to understand the end-goal needs of your soil and rock testing programs. MEC’s laboratory experts closely integrate soil and rock testing to provide material parameters that fit your engineering needs. Our specialized soil and rock testing supports the complete characterization of soil and rock’s physical composition, its mechanical, hydrological, and thermal behavior. We perform the full suit of Soil and Rock Mechanics tests. For information about specific soil and rock tests, please contact us at materials.testing@MECinternational.us.
