TRI is internationally acknowledged for testing innovation as it relates to geosynthetic materials testing. TRI staff and resources have initiated and/or uniquely invented a number of geosynthetic milestones incuding The Stepped Isothermal Method (SIM), thickness-dependent transmissivity, the constant flow geotextile permeameter, the 5-station tensiometer, the bending stiffness/resilient modulus test, and others.
The following represent continuing areas of TRI’s geosynthetic research:
- Interface Friction / Direct Shear
- Better Descriptions of GM Texturing
- Liner Integrity Surveys - Leak Location
Within the geosynthetics industry, there is all too often a tendency to mis-specify or over-specify a geosynthetic material. Problems in material specifications often result in an apparent "failure" in material even though the required test is inappropriate for the given material. In addition, wasted money is often spent on laboratory testing that provides no benefit in the context of material quality verification or investigation. In the worst cases, irrelevant specifications often lead to expensive delays in material acquisition and installation.
TRI's technical staff review geosynthetic material specifications to assure their relevancy to the material for which they exist. In addition, TRI staff may help develop specifications where none exist or where a new material is proposed for application. Through this work, TRI staff have saved significant money and time for our clients.
