Geosynthetic Clay Liner (GCLs)​

​

Geosynthetic Clay Liner (GCL) is widely used in environmental containment applications such as landfills, wastewater treatment facilities, mining ponds, and water reservoirs. It consists of a layer of bentonite clay encapsulated between geotextiles or bonded to a geomembrane, forming a low-permeability hydraulic barrier. In landfill systems, GCL functions as a critical liner component to prevent leachate migration and protect surrounding soil and groundwater from contamination. In other containment structures, it provides reliable seepage control, self-sealing performance when hydrated, and long-term environmental protection. Due to its ease of installation and consistent quality, GCL offers an efficient and cost-effective alternative to traditional compacted clay liners.
