High strength geosynthetic reinforcement products are often specified and are important to confirm with regard to characteristic strength. TRI is the highest quality laboratory in this regard as we employ a variety of state-of-the-art tension testing clamps and measurement systems. Included in this inventory of responsive tension testing technologies is the use of “Smart”-clamps, able to adjust gripping pressure based on the measured tension strength. These clamps adjust during testing to maximize the gripping pressure without damaging the material tested. Working together with non contact extensometry for strain measurement, TRI is able to test the strongest geosynthetic materials in the world.

TRI also tests high strength component yarns and tapes, and high strength geosynthetic stitched and mechanical seams.
