Geosynthetics Clay Liner is a kind of anti-seepage geosynthetics. The bentonite anti-seepage pad made by needle punching with highly expansive sodium-based bentonite filled between special composite geotextile and non-woven fabric can form many tiny fiber spaces, so that the bentonite cannot flow in one direction. When it encounters water, a uniform and high-density gel-like waterproof layer is formed inside the pad, which can effectively prevent water leakage. Geosynthetic Clay Liners (GCLs) are widely used in environmental containment applications, such as landfills, mining, and water containment. Here are TOP 6 Geosynthetics Clay Liner Manufacturers around the world. Hope it can help you choose products and suppliers better.
1. Geosynthetics Clay Liner Manufacturers – GSE Environmental (US)
GSE Environmental is one of the largest manufacturers of geosynthetic products, including GCLs. They offer a wide range of GCL products designed for various environmental and containment applications.
1.1 Advantage:
1.11 High anti-seepage performance
– GSE’s GCL utilizes high-quality sodium-based bentonite as the core material. This material ensures an extremely low permeability coefficient, typically around 10−9. Consequently, it effectively prevents the penetration of liquids and pollutants. Moreover, the design enhances environmental protection and containment performance. Additionally, the product meets rigorous industry standards for reliability and durability. Therefore, GSE’s GCL is a trusted solution for various geotechnical applications.
1.12 self-healing ability
– Bentonite can fill small holes or cracks in the GCL after swelling in water, forming a self-healing barrier and enhancing the anti-seepage effect.
1.13 Multiple product options
– GSE offers a variety of GCL products (such as needle-punched type, sutured type, film-coated type, etc.) to meet different engineering needs.
1.2 Disadvantage:
1.21 Limited mechanical strength
Although GCL has a certain tensile strength, it may be punctured or damaged under certain high stresses or sharp objects (such as stones), requiring additional protective layers (such as geomembranes or geotextiles).
1.22 High construction requirements
The installation of GCL demands precise construction techniques. Proper joint connections are crucial to prevent gaps or insufficient overlap. Any gaps or overlaps can compromise the overall anti-seepage performance. Therefore, careful attention is required during the laying process. Additionally, skilled workers must ensure seamless integration of the material. This guarantees the effectiveness of the anti-seepage system. Ultimately, meticulous installation preserves the integrity and functionality of the GCL.
1.23 High cost
Although the installation cost of GCL is relatively low, its material cost may be higher than that of traditional clay liners, especially when high-performance membrane-covered GCL is required.
