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's Committee D35 and ISO TC 221 for geosynthetics testing, and assure the most up-to-date, state-of- the-art testing systems and standard operating procedures for all sponsored work.

Operating in one to three 9-hour shifts per day, depending on time of year and the related level of sample traffic, TRI is well known for its rapid turnaround time service. This is crucial to construction driven installation schedules. All destructive seam testing is performed the SAME DAY as sample receipt.
