Geosynthetic Clay Liner

Geosynthetic clay liners (GCL) is a factory-made hydraulic barrier consisting of a layer of bentonite or other extremely low permeability material supported by geotextiles and/or geomembranes and mechanically fixed by acupuncture, stitching or chemical bonding. together. According to environmental laws, any leakage from landfills must be collected and properly disposed of, otherwise contamination of surrounding groundwater can cause serious environmental and/or ecological problems. The lower the hydraulic conductivity the more effective the Geosynthetic clay liners will be at retaining seepage inside of the landfill. Bentonite composed predominantly (>70%) of montmorillonite or other expansive clays, are preferred and most commonly used inThe main component of bentonite (> 70%) is montmorillonite or other expanded clay, which is preferred, the most commonly used in Geosynthetic clay liners. A general Geosynthetic clay liners the building will consist of two layers of geosynthetic material that are stitched together and contain a layer of natural or processed sodium bentonite. Typically, woven and/or nonwoven fabric geosynthetic materials are used, but polyethylene or geomembrane or geogrid geotextile materials have also been incorporated into or substituted for the fabric layer to increase strength. Geosynthetic clay liners are produced by a number of large companies in North America, Europe and Asia. The U.S. Environmental Protection Agency currently regulates the construction and design of landfills in the United States through several regulations.

ADVANTAGES:

Effective alternative to compacted clay with much larger installation coverage per day.
Superior tensile strength and self-healing capability solves cracking and leaking problems.
Strong mechanical bond that contributes to extensive shear strength thus provide excellent stability in challenging slope applications.
Simple deployment technique that requires no specialist labor and equipment.

Geosynthetic Clay Liner (GCL), also known as a geocomposite clay lining, consists of two layers of non-woven material, including bentonite and needled together to form a thick blanket layer, primarily used for landfill lining. The Geosynthetic Clay Liner function is similar to that of geomembrane, it has a relatively low hydraulic conductivity, prevents the infiltration of contaminants, and has been widely used as a landfill lining system to prevent fluid or containment. In addition to acting as a cover or backing for landfills, the Geosynthetic Clay Liner can be configured to meet specific shear strength and stability for any application, including groundwater protection covers, rainwater management ponds, and any ponds, dams, etc.

Geosynthetic Clay Liner (GCL) is a mature sealing product in the geological environment industry. They are used as covers and linings in landfills, as secondary containment vessels for fuel storage facilities, and in a variety of other closed structures such as dams, canals, rivers and lakes. Spread out like a carpet to provide a durable, impervious lining, Geosynthetic Clay Liner consists of a layer of high-swelling sodium bentonite sandwiched between two geotextiles. Canadians are manufactured around the world with different technologies Geosynthetic Clay Liner, A nonwoven geotextile is mechanically bonded to another nonwoven or woven geotextile by bentonite by needling. GCL's low hydraulic conductivity is primarily used to replace thicker, hard-to-build compacted clay linings to provide a barrier to liquids and gases, while providing technical and economic advantages.
