Soil Mechanics
Copyright 2015 - Advanced Terra Testing, Inc.
Advanced Terra Testing's (ATT) Soil Mechanics Division is responsible for performing a broad range of basic soils classification tests to sophisticated static triaxial and cyclic triaxial tests.

Testing performed by ATT follows established American Society for Testing Materials (ASTM) recommended procedures, Corp of Engineers (COE) procedures, or United States Bureau of Reclamation (USBR) procedures where ASTM standards are not available. The testing equipment and instrumentation utilized is routinely calibrated, traceable to the National Institute of Standards and Technology (NIST).

ATT utilizes a Material Testing System Corporation (MTS) closed-loop electro-hydraulic dynamic soil testing system. The equipment is specifically designed to allow for testing of a full range of standard triaxial and cyclic triaxial tests.
