Geosynthetics Clay Liner (GCL)

Geosynthetic Clay Liner (GCL), also known as bentonite geosynthetic clay liner, is a new type of geosynthetic material. It is manufactured using graded natural sodium bentonite and selected additives as raw materials. Through a needle-punching process, the bentonite particles are securely encapsulated between a nonwoven geotextile and a woven plastic geotextile, forming a blanket-type waterproof liner.

Bentonite GCL combines the advantages of geosynthetic materials with excellent impermeability, providing outstanding waterproof and seepage-control performance.

Forms a low-permeability barrier that effectively prevents water and liquid migration.

Prevents contaminants from entering soil and groundwater systems.

Supplied in rolls, allowing fast and efficient on-site installation.

Maintains stable waterproof performance over extended service periods.

Conforms well to uneven subgrades, ensuring continuous barrier performance.

Sodium bentonite swells upon hydration, sealing minor cracks and punctures.

Geosynthetic Clay Liner (GCL) is a geosynthetic material specifically designed for anti-seepage and waterproofing applications. It is widely used in artificial lakes, landscape water features, landfills, underground garages, roof gardens, swimming pools, oil depots, and chemical storage facilities, providing reliable and long-term seepage control.
