TRI/Environmental, Inc. was established to address health, safety, and environmental concerns primarily for commercial clients. It focuses on protective clothing evaluation, development, and certification; analytical chemistry testing services; materials testing and characterization; biological testing; compressed air testing; and geosynthetics engineered materials designed to enhance or alter the behavior of soils.

About Us

TRI/Environmental, Inc. (TRI) is an independent, third party, geosynthetics firm providing geosynthetics testing and research services to the international community. TRI is unaffiliated with any manufacturer or engineering firm, and thus provides non-competitive services to regulators, manufacturer, engineering firms, contractors and installers.

TRI provides laboratory conformance/verification testing as well as performance related studies. In addition to routine index testing in accordance with ASTM, ISO, BS, DIN and GRI test methods, TRI also provides standardized interface friction, permeability, creep and stress-rupture, transmissivity, gradient ratio, UV-resistance, chemical resistance, and accelerated time-temperature creep and stress rupture testing. Materials tested include:Geomembranes

  • Geotextiles
  • Geocomposites
  • Geogrids
  • Geostraps
  • Prefabricated Vertical Drains
  • Geosynthetic Clay Liners
  • Synthetic Yarns and Straps
  • Plastic Pipe
  • Roofing and Green Roofing Materials
  • Erosion Control Mulches, Waddles, Logs, Blankets, and Turf Reinforcement Mats

TRI's personnel 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.


Conformance/Verification Testing Services

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.

Unsaturated Soil Services

TRI offers a Salt Water Character Curve(SWCC) package that includes the following data: SaturatedHydraulic Conductivity – ASTM D 2434 or ASTM D 5084 depending on the flow rate ofthe soil. Moisture Content, Bulk Density, and Total Porosity. 5-7 Point Soil Water Characteristic Curve, Wetting or Drying. Curve fitting using both the van Genuchten and Brooks-Corey methods.
