TRI was the first laboratory accredited by the Geosynthetics Accreditation Institute (GAI) in the early 1990s and continues to maintain and grow an impressive range of accredited test method capabilities related to geosynthetics testing. In recent years, TRI has added accreditation for a growing number of erosion control products (ECP) and sediment retention device(SRD) test procedures, as well as, AMRL/AASHTO accreditation for an increasing number of geotechnical tests.
TRI’s laboratories are operated in accordance with the corporate Quality Management System. This system includes rigorous requirements for every aspect of operations from equipment calibrations and the use of internal reference materials to personnel training and up-to-date standard operating procedures. Both in-house audits by the corporate quality manager and periodic independent audits associated with maintaining accreditations are included in the Quality System.
TRI employs trained technicians, standard operating procedures (SOPs), and the necessary equipment for all standardized test methods, and many non-standard test methods. All standard test methods can be run at any time. Typically, index testing can be completed and reported within one week of sample receipt (depending on existing workload). Bench-scale and large-scale testing turn-around also depends on lab workload, but is typically 6 to 8 weeks, including report issuance.

Mr. C. Joel Sprague
Joel Sprague, P.E., TRI’s Senior Engineer provides technical oversight of all of TRI’s erosion and sediment control testing.
Mr. Sprague is a long-time member of the senior technical staff specializing in research, development, and application of geosynthetics, plastic pipe, and erosion and sediment control technologies. He is a registered professional engineer in North Carolina, South Carolina, and Georgia.
Mr. James (Jay) Sprague
Jay Sprague, TRI’s Field Lab Director provides operational management of TRI’s erosion and sediment control index and bench-scale testing efforts, and provides direction to site technicians on site operations and testing protocol.
Mr. Sprague has been integrally involved with implementing large-scale test methods, including the construction and maintenance of the state-of-the-art facilities that make TRI the only independent commercial laboratory offering such a wide array of performance testing capabilities.
Mr. Jarrett Nelson
Special Projects Manager
Jarrett Nelson, TRI’s Special Projects Manager provides oversight for all specialty testing performed at TRI’s corporate lab in Austin, Texas.
Mr. Nelson has been involved with the development of most of the testing protocols now incorporated into ASTM’s standard test methods related to erosion and sediment control systems/materials.
