Company Information
TRI/Environmental, Inc. (TRI) is an independent, third party, geosynthetics firm which provides testing and research services to the international community. TRI provides laboratory conformance/verification testing as well as performance related studies. TRI is the first laboratory in the world to be accredited by the Geosynthetics Accreditation Institute and is distinguished as having the most extensive list of accredited tests. In addition to routine testing in accordance with ASTM, ISO, BS, DIN and GRI test methods, TRI provides interface friction, permeability, creep and stress-rupture, transmissivity, gradient ratio, UV-resistance, chemical resistance, carbonyl end group, viscosity, and accelerated time-temperature testing. TRI's staff are active throughout the world's standards development organizations and routinely provide short courses, seminars and tailor-made training services to those learning about geosynthetics.

TRI earned a superior reputation as an internationally acclaimed, highest quality testing and research facility. TRI’s geosynthetics laboratories and governing quality assurance system are accredited by the Geosynthetics Accreditation Institute (GAI). TRI is proud to be the first testing laboratory to achieve this accreditation, and is currently distinguished as holding the most comprehensive (91 tests) accreditation among commercial testing laboratories. Our accreditation documentation may be e-mailed upon request and independently verified by visiting the GAI home page at www.geosynthetic-institute.org.

TRI Releases Erosion and Sediment Control Video Series

Chelsea Thompson's video series documents the large-scale erosion and sediment control testing at TRI Environmental's Denver Downs Research Facility in Anderson, South Carolina. Seen here: A video on testing for ASTM Standard D7351. This is 1 of 9 videos in TRI's new series.

25 May 2011 - In the fall of 2010, as a part of a training day in South Carolina for an International Erosion Control Association (IECA) state group, videographer Chelsea Thompson conducted interviews and captured footage of full-scale erosion and sediment control testing procedures at TRI Environmental's Denver Downs Research Facility (DDRF) in Anderson, South Carolina. Those videos have now been uploaded for open access online.

The nine videos in the series address performance issues associated sediment retention devices (SRDs), including silt fence, ASTM D 7351 toe-of-slope testing, curb inlet filters along gutter lines, turbidity treatments, inlet filters for area inlets, ASTM D 6459 slope testing, sediment traps and baffles, sediment bags, and ASTM D 7208 check structure testing in trapezoidal channels.
