PRODUCT DETAILS
1. Certified Excellence in Hydraulic Containment
Longxiang New Materials is dedicated to manufacturing Geosynthetic Clay Liners (GCLs) that not only meet but often exceed global regulatory requirements. Our GCL products are certified to rigorous ASTM International Standards and serve as reliable, high-performance hydraulic barriers for the most critical environmental and civil engineering projects.
We use laboratory-verified natural Sodium Bentonite clay, encapsulated in high-tenacity geotextiles, creating an engineered composite that delivers ultra-low permeability and proven long-term sealing integrity. Choose our ASTM Standard GCLs for guaranteed compliance and peace of mind on your high-stakes containment needs.
2. Adherence to Global Standards
Quality assurance is the foundation of our manufacturing process. Every batch of GCL undergoes strict, independent testing to ensure performance meets or surpasses the following key standards:
ASTM D5887 (Hydraulic Conductivity): Verifies the ultra-low permeability necessary for effective containment.
ASTM D5993 (Mass per Unit Area): Guarantees the consistent and required loading of sodium bentonite clay within the product.
ASTM D6496 (Peel Strength): Ensures the mechanical bond of our reinforced GCL remains intact during installation and service life.
GRI-GCL3 Specification: Compliance with the Geosynthetic Research Institute's widely recognized minimum specification requirements for GCLs.
3. High-Performance Benefits for Engineers
Proven Low Permeability: Our GCL consistently achieves a hydraulic conductivity of $\le 5 \times 10^{-11} m/s$, which is often orders of magnitude better than typical compacted clay liners.
Engineered Self-Sealing: The high-swell sodium bentonite clay immediately self-seals minor punctures or tears that might occur, maintaining the integrity of the hydraulic barrier.
Superior Durability: The GCL structure resists damage from differential settlement and freeze-thaw cycles better than rigid barriers.
Certified Shear Strength: For reinforced variants, the mechanical bonding is quantified and certified to handle high shear loads, crucial for slope and embankment stabilization.
4. Critical Applications Requiring Certification
Projects demanding guaranteed performance rely on our ASTM Standard GCLs:
Hazardous Waste Containment: Ensuring zero leakage for toxic industrial residues.
Regulated Landfill Base Liners: Meeting strict government requirements for barrier systems in Municipal Solid Waste (MSW) landfills.
Water Reservoirs & Dams: Providing certified, long-term anti-seepage solutions for potable water infrastructure.
Environmental Remediation: Used in brownfield sites and environmental cleanup operations where verified performance is mandatory.
