Product Description
Geosynthetic Clay Liner (GCL) is an environmentally friendly composite waterproof impermeable material featuring bentonite particles sandwiched between woven and nonwoven geotextile layers. Manufactured through specialized processes using acupuncture methods, GCL offers compact dimensions, lightweight construction, excellent flexibility, and reliable sealing capabilities. Ideal for uneven settlement applications, this material provides effective segregation and anti-leakage solutions for environmental engineering, landfill emissions, underground reservoirs, and infrastructure projects.

Key Advantages
- Superior Compactness: Sodium bentonite forms a high-density 3mm diaphragm with permeability equivalent to 100 times that of 30cm thick clay liners
- Permanent Waterproof Performance: Natural sodium bentonite base ensures no aging or corrosion over time
- Simple Installation: Requires only bentonite powder, nails, and washers – no heating or pasting needed
- Temperature Resistance: Maintains flexibility and performance in cold weather conditions
- Structural Integration: Bentonite expands 20-28 times to repair concrete surface cracks up to 2mm
- Environmentally Friendly: Natural inorganic material that is non-toxic and harmless to the environment
