GRI GCL3 ASTM D5887, D6766 Index Flux through GCLs using Flex Wall Permeameter

This video describes ASTM D5887 “Test Method for Measurement of Index Flux Through Saturated Geosynthetic Clay Liners Specimens Using a Flexible Wall Permeameter” as it applies to GRI GCL3: Standard Specification for “Test Methods, Required Properties and Testing Frequency for Geosynthetic Clay Liners (GCL).” This specification was developed by the Geosynthetic Research Institute (GRI) under the auspices of the Geosynthetic Institute (GSI), with the cooperation of the member organizations for general use by the public. For further information, please consult our website: www.geosynthetic-institute.org. GSI constitutes a diverse assembly of stakeholders who actively engage in the manufacturing, design and use of geosynthetics as engineering materials. GSI’s mission is to develop and transfer knowledge, assess and critique geosynthetics, and provide service to its member organizations. One of the major objectives of the institute is to develop and implement generic specifications of geosynthetics used in Civil Engineering applications all over the world.
