Bentonite Geosynthetic Clay Liner(GCL) is a new type of geosynthetic material. It is a blanket-like waterproof membrane made of graded natural sodium bentonite particles and corresponding additives mixed as raw materials. The bentonite particles are fixed between geotextiles and plastic woven fabrics through a needle punching process. Bentonite waterproof blanket not only has all the characteristics of geotechnical materials, but also has excellent waterproof (seepage) performance.

Bentonite Geosynthetic Clay Liner(GCL)Description of Bentonite Geosynthetic Clay Liner(GCL)

Bentonite Geosynthetic Clay Liner(GCL) is filled with highly expandable bentonite inside non-woven fabric, which is used to waterproof and prevent leakage in some occasions. It is filled with highly expandable sodium bentonite between a special composite geotextile and non-woven fabric. The bentonite anti-seepage mat made by acupuncture method can form many small fiber spaces so that the bentonite particles cannot flow in one direction. When exposed to water, a uniform and high-density gel-like waterproof layer is formed inside the pad, effectively preventing water leakage. Bentonite waterproof blanket is a new type of waterproof material, which is more environmentally friendly than other waterproof materials.

Bentonite Geosynthetic Clay Liner(GCL)Benefits of Bentonite Geosynthetic Clay Liner(GCL)

Bentonite Geosynthetic Clay Liner(GCL) consist of clay material and geotextile.About the clay material, it is usually bentonite, which sandwiched between two layers geotextiles. This lining mechanism is mechanically bonded by needle punching from one nonwoven geotextile through the bentonite to the other nonwoven or woven geotextile. The bentonite swells and extrudes through the geotextile fabric at the overlap, forming a seal by producing a dense and uniform clay barrier with the same hydraulic qualities in all parts of the clay liner.Therefore, bentonite waterproof blankets usually have the following characteristics:

  • ◆1.Compactness: Sodium bentonite forms a high-density diaphragm under water pressure and has strong self-retaining water properties.
  • ◆2.Has permanent waterproof performance.
  • ◆3.Easy construction and short construction period: Compared with other waterproof materials, construction is relatively simple. GCL has the shortest construction period among existing waterproof materials.
  • ◆4.Not affected by temperature: It will not break brittlely in cold climate conditions.
  • ◆5.Integration: Integration of waterproof materials and objects.
  • ◆6.Green and environmentally friendly: Bentonite is a natural inorganic material that is harmless to the human body and has no special impact on the environment. It has good environmental performance.

Bentonite is a natural clay formed by weathering of volcanic ash. Its chief constituent is the clay mineral montmorillonite.
Bentonite is distinguished from other clays by its extreme fineness, highly absorbent nature and curious property of swelling in water.
