PRODUCT DETAILS
1. product overview
Longxiang New Materials specializes in providing Geosynthetic Clay Liners (GCLs) engineered specifically for challenging environmental and hydraulic applications. Our GCL Liners utilize premium natural Sodium Bentonite clay, encapsulated between high-strength geotextiles, to form an ultra-low permeability barrier.
Whether you are designing a new landfill cell, constructing an artificial pond, or managing mining leachates, our GCLs offer a robust, self-sealing, and cost-effective waterproofing solution that exceeds the performance of traditional compacted clay.
2. Applications
A. Landfill & Waste Management
Primary Barrier: Used as the primary or secondary lining component in composite liner systems for Municipal Solid Waste (MSW) and hazardous waste landfills.
Final Covers (Caps): Provides a long-term, low-maintenance seal for landfill closures, minimizing rainwater infiltration and leachate generation.
Benefits: Reduces the required thickness of the barrier layer, maximizing valuable disposal space and ensuring regulatory compliance.
B. Ponds & Water Impoundments
Leak Prevention: Ideal for waterproofing retention ponds, irrigation reservoirs, and decorative artificial lakes.
Erosion Control: The GCL structure provides immediate stabilization to the underlying soil, preventing liner damage from soil movement.
Benefits: Dramatically reduces water loss in high-porosity soils, saving resources and ensuring project longevity.
C. Mining & Industrial
Heap Leach Pads: Essential for containing cyanide and acid drainage solutions, protecting groundwater from toxic leachates.
Tailings Storage Facilities (TSFs): Offers a secure base liner for the long-term containment of mining residues.
Benefits: Resistant to chemical attack and provides the critical hydraulic conductivity required for safe mining operations.
3. Core Advantages
Ultra-Low Hydraulic Conductivity: Our GCLs consistently achieve a permeability of $\le 5 \times 10^{-11}$ m/s, offering superior long-term containment.
Time-Saving Installation: Rapid deployment saves significant construction time compared to sourcing, preparing, and compacting meters of native clay.
Self-Healing Capability: The contained sodium bentonite swells and fills small holes or cracks that may occur during placement, ensuring a continuous seal.
Environmental Reliability: GCLs provide a stable, long-lasting barrier that remains effective even when subjected to freeze-thaw cycles and desiccation.
4. Technical Specifications
We adhere strictly to ASTM International and GRI-GCL3 standards. All GCL batches are tested for parameters critical to containment security, including Bentonite Mass, Swell Index, and Hydraulic Conductivity.
| Specification Focus | Key Metric | Importance to Project |
|---|---|---|
| Bentonite Core | $\ge 4000 g/m^2$ | Ensures ample swelling capacity for sealing. |
| Permeability | $\le 5 \times 10^{-11} m/s$ | Guarantees environmental protection and leak prevention. |
| Shear Strength | ASTM D6243 | Critical for slope stability in landfills and dams. |
