The durability of geosynthetics and geosynthetic systems is often measured to assure long-term performance. TRI is a world-wide leader in durability testing and offers considerable capabilities to meet regulatory-driven or product development needs. TRI responds to both environmental and load/construction durability concerns via large-scale and bench-scale testing of geosynthetics and their component materials. Some of the durability testing services and relevant standards are listed below.
