Geosynthetic Research Institute

The Geosynthetic Research Institute (GRI) is an organization dedicated to studying and testing geosynthetic materials, which are synthetic products used in construction and civil engineering, such as liners, barriers, and reinforcement fabrics. GRI provides research, testing, certification, and technical support to ensure these materials perform reliably in applications like landfills, roads, and drainage systems. Their work helps improve infrastructure safety, durability, and environmental protection by establishing standards and advancing knowledge in geosynthetics technology.
