Since the late 1980s, military, federal, state, and local law enforcement have incorporated NLW or less-than-lethal technology into their daily efforts to discourage or prevent hostile action, temporarily disable attackers, suppress unruly crowds, quell prison riots, and reduce loss of life. Dispersing a crowd safely and quickly with an NLW has been an ongoing topic…
In 2018, the Liner Integrity Survey and Assessment Division of TRI performed a record number of electrical leak location (ELL) surveys encompassing over 10 million square feet. TRI’s Australasia, China, and Brazil offices also continued to offer this service. TRI’s new Africa office is now also performing this service in South Africa, where it is…
For a number of years, TRI has been evaluating the short- and longterm structural integrity of buried stormwater quality units. In 2018, we initiated full-scale hydraulic evaluations of manufactured treatment devices (MTDs) and nutrient removal products. MTD testing is based on ASTM standards (C1745 and C1746), while nutrient removal testing evolves from collaboration with product…
The geohazard of rockfall affecting road networks is of considerable interest to highway engineers working in mountainous terrain. Some of the principal measures to protect against rockfall involve rockfall checkfences, barrier fences, heavy-duty mesh netting, rockfall catch areas, sprayed fibre concrete (fibrecrete), and modifications to drainage systems including channel training works. TRI is very active…
TRI’s unique, independent in-plant geosynthetic sampling services are widely recognized throughout the worldwide materials procurement industry. Still, we often encounter questions regarding in-plant sampling procedures, the true independence or non-independence of part-time sampling procedures, and general policies regarding materials access, and safety. These procedures are unique to each geosynthetic manufacturing plant and TRI’s in-plant sample…
2018 saw the full implementation of new accounting and laboratory information management systems (LIMS). These efforts streamlined sample tracking and customer response times while providing us real-time information regarding project and laboratory status. These efforts will continue in 2019 as newer features of our LIMS system are evaluated and implemented to automate and streamline in-house…

Segmental Concrete Block Units and Pullout TRI’s geosynthetic-interaction laboratory experienced an exceptional year in 2018. The potential of our large-scale, high-capacity load frame capable of applying normal and shear forces of up to 440 kN (100,000 lbf) aided us in the evaluation of mechanical and friction connections of geosynthetics to large block systems. Operating in…
In July of 2018, TRI was very pleased to announce the establishment of TRI Africa Environmental Services Pty. Ltd. (TRI Africa) headquartered in Johannesburg, South Africa. This TRI company joins our global independent third-party geosynthetics/geotechnical testing and research centers with operating service centers in the United States, Brazil, China, Australia and India. TRI has successfully…
