Geosynthetic Clay Liner GCL Malaysia
Geosynthetic Clay Liner GCL Malaysia (GCLs) are factory manufactured hydraulic barriers consisting 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. Due to environmental laws, any seepage from landfills must be collected and properly disposed of, otherwise contamination of the surrounding ground water could cause major 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 in Geosynthetic clay liners. A general Geosynthetic Clay Liner GCL Malaysia construction would consist of two layers of geosynthetics stitched together enclosing a layer of natural or processed sodium bentonite. Typically, woven and/or non-woven textile geosynthetics are used, however polyethylene or geomembrane layers or geogrid geotextiles materials have also been incorporated into the design or in place of a textile layer to increase strength. Geosynthetic clay liners are produced by several large companies in North America, Europe, and Asia. The United States Environmental Protection Agency currently regulates landfill construction and design in the US through several legislations.
Advantages:
- An effective alternative to compacted clay with much greater daily installation coverage.
- Superior tensile strength and self -healing ability solve the problem of cracking and leakage.
- Strong mechanical bonds that contribute to wide shear strength thus providing excellent stability in challenging slope applications.
- Simple application technique that does not require specialized manpower and equipment.
Geosynthetic Clay Liner GCL Malaysia (GCL), also known as Geocomposite Clay Liner consists of two layers of material such as nonwoven fabric that combine bentonite and needle together to form a thick blanket layer, mainly used for landfill lining. Geosynthetic Clay Liner GCL Malaysia works like a geomembrane that has a relatively low hydraulic conductivity that prevents the secretion of contaminants and that has been widely used as a TPA Layer System that resists liquids or containment. In addition to serving as a Landfill cover cover or base liner, Geosynthetic Clay Liner GCL Malaysia can be configured to meet specific shear strength and stability for each application including groundwater protection covers, stormwater management ponds and ponds, dams and more.
Geosynthetic Clay Liner GCL Malaysia (GCL) is a well -established sealing product in the geoenvironmental industry. They are used in landfill applications as cover and base liner, secondary retention for fuel storage facilities, as well as in various other retention structures such as dams, canals, rivers, and lakes. Rolled like a rug to provide a durable liner, Geosynthetic Clay Liner consists of a layer of sodium bentonite with high swelling between two geotextiles. Manufactured worldwide with different techniques, the Canadian -made Geosynthetic Clay Liner GCL Malaysia, is bonded mechanically by piercing a needle from one nonwoven geotextile through bentonite to another nonwoven or woven geotextile. The low hydraulic conductivity of GCL is used primarily as a substitute for dense and difficult -to -construct clay liners to provide a barrier to liquids and gases, which offers technical and economic advantages.
