    Geosynthetic Clay Liner Waterproof Blanket Bentonite

    ●Composition: Made of sealing bentonite powder or particles sandwiched between two layers of geotextile using needle punching technology.

    ●High-Quality Materials: Made of natural sodium-based bentonite granules known for their high expansion performance.

    ●Key Features:

    Puncture Resistance: The product exhibits enhanced resistance to puncturing.

    Tensile Strength: High tensile strength ensures durability and longevity.

    Expansion Capacity: Excellent expansion and high water absorption capabilities.

    ●Mechanism: Upon contact with water, the bentonite hydrates and expands, forming an impermeable gel.

    ●Functionality: Effectively provides sealing and anti-seepage performance.

      Production Line Process and Raw Materials

      Our company adopts latest domestic production equipment, and the raw materials are natural sodium bentonite particles with high expansion.
      In order to ensure 100% product pass rate, quality control department of the company to implement the production line inspection and random inspection of finished products, for the quality of product of the “Zhonglong” brand to provide double insurance.
