Geosynthetics Testing

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 distinguished as holding the most comprehensive (161 tests) accreditation in the world. TRI has been testing and evaluating geosynthetics materials for over two decades and has earned a superior reputation as an internationally acclaimed, highest quality testing and research facility. Our staff are active on ASTM D35 and ISO TC 221 for geosynthetics testing,  assuring the most up-to-date, state-of- the-art testing systems and standard operating procedures for all work.

We classify tests with geosynthetics in two major groups of testing: Geosynthetic and Soil-Geosynthetic Interaction.  For more detail, please visit the Tests & Capabilities page.
