GCL-5 consists of a layer of bentonite encapsulated between two layers of geotextiles (non-woven geotextile and woven polypropylene geotextile), needle punched together and glued on one side with a layer of non-woven geotextile and HDPE Film , for maximum performance under various field conditions. This integrated matrix of bentonite and needle punched fibers provides high shear strength and GCL-5 maintains low permeability even under adverse installation conditions. GCL-5 features high internal shear strength properties for steep slope applications
