Advanced Terra Testing, Inc. (ATT) is a full-scope, state-of-the-art geotechnical testing laboratory providing advanced capability in soil & rock mechanics and geosynthetics testing services. Located 20 minutes west of Denver, Colorado in Lakewood, ATT has performed more than 1000 projects for over 400 commercial and governmental clients (including major geotechnical programs at several U.S. DOE and DOD sites). ATT has provided geotechnical testing services for projects in all of the 50 states and 23 foreign countries. Our principals and associates have more than 140 years of experience in applied geotechnical testing.

About Us

Laboratory Staff

ATT maintains an experienced laboratory staff with the full spectrum of technical, project management, report preparation, and administrative expertise necessary to efficiently conduct the laboratory's operations. Cumulatively, these individuals possess 10 undergraduate and graduate degrees, have more than 140 years of experience, and have successfully conducted hundreds of testing campaigns involving sample preparation, laboratory analysis, and results reporting for literally tens of thousands of individual samples.

The heart of ATT's ability to provide quality service lies in the experience, dedication and training of the lab's personnel. In addition to their eminent academic and practical qualifications, each individual must pass training in our rigorous Quality Assurance, sample handling and tracking, standard technical, and Radioactive Materials License procedures. Current OSHA and NICET training is maintained for staff working in functional testing and/or with site access requirements.


Christopher J. Wienecke, Co-owner - 28 years of experience in geotechnical testing and field exploration, including the design and execution of geotechnical sample collection programs, laboratory testing campaigns, and the interpretation and use of laboratory data. He is active in the development of advanced laboratory techniques, sitting on both the ASTM D 18 (Soil & Rock Mechanics) and D 35 (Geosynthetics) Committees; he also acts as an adjunct Instructor at the Colorado School of Mines.

Duke C. Wilson, Co-owner - 40 years of experience in materials testing, test equipment design and construction, and laboratory setup and operations; he has also had extensive experience in calibration and maintenance of sensor technologies (e.g., temperature, pressure, flow rate) and recording systems. With applied work in fracture mechanics and fatigue and tension testing, he has been responsible for the performance of thousands of geotechnical testing programs.


Since its founding, Advanced Terra Testing has invested more than $1 million on the acquisition, design, construction, calibration and proof testing of geotechnical laboratory equipment; virtually all of ATT's test apparatus has been custom designed and constructed to the lab's exacting standards for test accuracy and production capacity. As a result, ATT offers state-of-the-art geotechnical testing capability in soil mechanics, rock mechanics and geosynthetics, and, in many cases, the lab offers testing capacities and/or protocols which are unique in the industry. This same innovative equipment design and construction capability has often been applied to unique client testing requirements, ensuring that virtually any soil, rock or geosynthetic testing program can be accommodated.


Field Services

In response to increasing client needs and as a natural supplement to ATT's extensive geosynthetics testing capabilities, ATT established the Field Services Division in 1995. The role of the Field Services Division is in the support of project specific Manufacturing Quality Assurance (MQA), Construction Quality Assurance (CQA), and forensic investigations involving applications of geosynthetics CQA services involve observing and documenting a ...

Soil Mechanics Testing Service

Advanced Terra Testing's (ATT) Soil Mechanics Division is responsible for performing a broad range of basic soils classification tests to sophisticated state of the art static triaxial and cyclic triaxial tests.
