What is Geosynthetic Clay Liner (GCL)? Applications, Structure, and Advantages

Reading Time: 3 minutesGeosynthetic Clay Liner (GCL) is one of the most advanced geosynthetic materials used in modern civil and environmental engineering. It consists of a thin layer of natural sodium bentonite sandwiched between two geotextile layers, mechanically bonded through needle punching. This structure creates a durable, impermeable barrier that prevents the passage of water and other fluids. Due to its efficiency, cost-effectiveness, and ease of installation, GCL has become a preferred alternative to traditional clay liners in many large-scale projects.
