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
