Product Description
Eco-Friendly Sodium Bentonite GCL – Durable Sealing Material
Sodium Bentonite Geosynthetic Clay Liner (GCL) is an environmentally friendly geosynthetic waterproof material manufactured using high-quality graded sodium bentonite as the core raw material. Through advanced needle punching technology, bentonite particles are securely fixed between geotextiles and woven fabrics, creating a sustainable sealing solution with no environmental pollution.
The primary component, sodium bentonite, is a natural mineral material that exhibits exceptional water swelling properties. Upon contact with water, it rapidly expands to form a dense, impermeable waterproof layer, delivering superior anti-seepage performance.
Key Performance Advantages
- Excellent flexibility and sealing performance
- High shear strength and durability
- Simple construction process with strong adaptability to uneven settlement
- Superior anti-seepage effect compared to compacted clay liners
- Resistance to chemical erosion for long-term project stability
- Smaller volume, lighter weight, and lower construction costs
Primary Applications
Ideal for environmental engineering projects requiring high anti-seepage performance including landfills, tailings dams, hazardous waste yards, industrial waste storage facilities, artificial lakes, landscape water systems, and underground infrastructure construction. Effectively addresses sealing, isolation, and anti-seepage challenges while preventing harmful substance leakage to protect soil and water resources.
Three-Layer Composite Structure
Top Layer: Protective geotextile that shields the middle bentonite layer from damage
Middle Layer: Sodium bentonite core providing the primary anti-seepage function
Bottom Layer: Woven fabric enhancing tensile strength and wear resistance
Middle Layer: Sodium bentonite core providing the primary anti-seepage function
Bottom Layer: Woven fabric enhancing tensile strength and wear resistance
All three layers are firmly bonded through needle punching technology, ensuring product stability and reliability.
