Overview of GeoTesting Express, Inc.
GeoTesting Express, Inc. (GTX) is the testing division of Geocomp Corporation. We provide the fastest turnaround time available for mechanical and physical properties testing services on soils, rocks, geosynthetics and other geo-materials. Since 1989 our internationally recognized laboratories have been providing high-quality testing services for a variety of projects ranging from tunnels, dams and nuclear-related facilities to deep excavations, landfills and retaining structures. GTX offers:
• Fastest turnaround available for high-quality testing services • Full complement of soil, rock and geosynthetic tests • Expert support from industry leaders • Highly qualified and experience field staff for CQA/CQC • The ability to handle large projects without a reduction in speed or quality • Fully accredited laboratories • Competitive pricing
To process large volumes of tests within a short period of time, we have developed processes and utilize automated equipment designed to perform tests at the maximum speed allowable by published standards. Examples of available turnaround times include:
Test Turnaround Test Turnaround Incremental Consolidation 36 hours Permeability 36 hours Triaxial Shear Series 48 hours Grain Size & Atterberg Limits 48 hours Direct Shear Series – Sand 24 hours Direct Simple Shear – Clay 48 hours Rock Triaxial 24 hours Rock Unconfined Compression 24 hours Interface Shear 24 hours Geosynthetic Conformance 24 hours
Validated by: United States Army Corps of Engineers Accredited by: American Association of State Highway and Transportation Officials (AASHTO) American Association for Laboratory Accreditation (A2LA) Geosynthetics Accreditation Institute – Laboratory Accreditation Program (GAI-LAP) GTX is audited at regular intervals as a requirement of the above referenced accreditation programs. Our quality system and our technical procedures are scrutinized during these audits, helping us ensure that the quality of our work is maintained at the highest possible level. In addition to voluntary laboratory audits, we also participate in several sample proficiency testing programs to benchmark our work. In order for GTX to maintain its accreditations, we must achieve a minimum score (typically within ±2 standard deviations from the average) on proficiency testing. GTX has also been audited against ASME NQA-1-1999 Quality Assurance Requirements for nuclear facility applications allowing us to provide testing in support of nuclear facility projects. Our quality program is designed to ensure the highest quality in our test equipment, processes and results. The centerpiece of this program is our quality manual which is designed to meet the requirements set forth in ANSI/ASQC Q9001-2000 and ISO/IEC Guide 17025-2005.

SVS11020_GTX_RockTesting
GeoTesting Express, Inc. (GTX), provides one-stop rock preparation and laboratory testing. Servicing the geotechnical, tunneling, mining and excavation industries, we provide rapid strength and index testing of rock samples. We can prepare test specimens from cobbles, boulders, blocks or cores with our equipment. We can also core specimens perpendicular to the direction of a core run.
Capabilities of GeoTesting Express’ Rock Testing
GeoTesting Express performs a full-range of tests on rock. We prepare and tests rock specimens in-house. Servicing the geotechnical, tunneling, mining and excavation industries, we provide rapid strength and index testing of rock samples. We can prepare test specimens from cobbles, boulders, blocks or cores with our equipment. We can also core specimens perpendicular to the direction of a core run.
We utilize specialized equipment and have developed detailed processes for preparing specimens to meet the specifications set forth in ASTM D4543: “Preparing Rock Core Specimens and Determining Dimensional & Shape Tolerances”, which is a requirement for any rock strength test. GTX is validated by the U.S. Army Corps of Engineers and accredited by A2LA for testing rock samples.
Rock requiring unconfined compression or triaxial compression testing must be prepared and meet very strict dimensional tolerances in accordance with ASTM D4543. Our technicians can prepare up to 8 rock specimens at one time with a higher degree of precision using our Okamoto surface grinder.
GTX is one of the few labs in the world that strictly adheres to the ASTM requirements for dimensional tolerances. Tests performed without well prepared surfaces will give much lower unconfined compressive strength which can mislead one to choose the wrong mining equipment.
GeoTesting Express utilizes state-of-the-art automated testing equipment to perform high-end strength testing of rock (Unconfined Compression, Direct Shear, Brazilian Tensile Strength, Elastic Moduli, Triaxial, etc.). Advantages of this equipment include:
• Complete electronic controls over test parameters & resultant report• Fast turnaround of test results• Standardized test report formats• Electronic report deliverables (including before & after
photographs of samples)
