What Does GCL Stand For?
GCL stands for Geosynthetic Clay Liner
GCL, or Geosynthetic Clay Liner, is a composite material typically consisting of a layer of sodium bentonite clay sandwiched between two geotextiles or geomembranes. It is widely used in environmental applications for containment and prevention of fluid migration, making it effective in landfill liners, waste containment, and environmental remediation projects. Its excellent impermeability, lightweight properties, and ease of installation contribute to its growing popularity in civil engineering and environmental protection initiatives.
