GCL consists of a layer of bentonite or other very low-permeability material supported by geotextiles and/or geomembranes, mechanically held together by needling, stitching, or chemical adhesives. A unique feature of increasing its volume on contact with water, resulted in a lack of permeability ,as well as self-healing feature are the advantages of this product. Also, it is efficient  in the field of transportation, geotechnical, hydraulic and other unique purposes.

 

Application of GCL

- Landfill Covers (or Caps) and Remediation Barriers—GCLs are used to inhibit the ingress of water and the escape of fluids and/or gases in the construction of solid or industrial waste facility cover or to cap contaminated soil.

- Canals, Streams, or Waterways Liners and Surface Impoundments or Ponds

- Environmental Protection—The function of the GCL in these applications is to inhibit hazardous liquids or constituents resulting from vehicle, railway, or airline incidents from entering a sensitive location in the local environment

- In applications in which a significant water head is maintained, GCLs are generally used in combination with an existing soil barrier or in combination with a geomembrane
