The annual letter from TRI Environmental to its clients and the general geosynthetics community merits review for a number of its highlights. The company notes the considerable expansion testing capabilities, both through the addition of key equipment and through the re-location of its outdoor, large-scale testing facility for trafficking studies and erosion and sediment control testing.
Furthermore, major staff additions in 2017, a record year for leak location services, expanded education and training offerings, and various in-house process updates have enhanced services and response times for the geotechnical field.
These company updates are interesting not just for the individual developments but for how they reflect larger movements in the geosynthetics field:
- The expanding need for liner integrity services (and service providers) and affiliated CQA
- The impact of coal ash on testing requirements
- The increasing importance trafficking research and material performance testing
- How large-scale testing is changing the way the field perceives and adopts erosion and sediment control systems and designs
TESTING CAPABILITIES, ENHANCED SERVICES & OTHER HIGHLIGHTS
TRI Southeast Expansion
The large-scale, outdoor testing facility has moved from Anderson to Greenville, South Carolina. The new location is not only more directly accessible from the Greenville Airport for site visitors but much larger. The 10-acre space includes a 4.5-acre lake to support various hydraulic tests.
New Accelerated Pavement Tester (APT)
The Accelerated Pavement Tester rolling wheel load test is very similar to a real roadway but is built in a more controlled environment. Built at full-scale in a concrete-lined pit rather than in a soil trench, the APT-applied load is quicker to traffic since it is done with an accelerated testing device rather than an actual vehicle. The test pit is 11 ft wide x 36 ft long x 4 ft deep.
Interface Friction / Direct Shear Testing capabilities
Coal ash cell closures on existing and new storage cell modifications have greatly increased the need for interface friction testing. TRI now has 26 shear boxes, with five frames dedicated to high loads and five dedicated to low loads (to negate bias) .
Geotechnical Laboratory Developments
The growth in geotechnical tests has led to the addition of Amanda Salinas as the geotechnical lab coordinator. The rapid turn time for advanced testing is now supported by over 50 flexible wall permeability, 20 triaxial, 9 direct shear, 12 incremental consolidation, three CRS, and DSS capabilities.

Liner Integrity Services
Abigail Gilson’s liner integrity survey division had a record year for leak location surveys (47 projects, 15 million+ ft. of liner). More than 10 other projects were handled by companies trained or assisted by TRI or using TRI equipment. New equipment will be released soon. The company also brought CQA training internationally again, including through education sessions in South Africa and Australia.
Internal Process Improvements
The past year saw the company on-board new accounting, business, and sample tracking systems for better customer service and response
