Geosynthetic Landfill Liner Manufacturer
Dual Barrier Protection: Combines HDPE geomembrane (physical barrier) + GCL (self-sealing clay) for zero leakage.
Certified Quality: 100% virgin material, compliant with ASTM GRI-GM13 & ISO 9001.
Chemical Resistance: Withstands aggressive leachate, acids, and alkalis for long-term durability.
Slope Stability: Textured HDPE surface prevents slippage on steep landfill slopes.
Cost-Efficient: Wide-width rolls (up to 8m) reduce welding time and installation costs.
Product Details: Landfill Liner System (HDPE + GCL)
1. Product Overview
[YourBrand] supplies high-performance composite Landfill Liner Systems engineered for environmental containment. By integrating HDPE Geomembranes with GCL Bentonite Clay Blankets, we provide a dual-barrier solution that prevents leachate migration and protects groundwater resources. Our systems are designed to meet the stringent requirements of municipal, industrial, and hazardous waste projects worldwide.
2. Key Features & Benefits
Dual-Barrier Protection: Combines a high-strength HDPE geomembrane with a self-sealing GCL layer for near-zero permeability.
Regulatory Compliance: Manufactured in strict accordance with ASTM GRI-GM13 and ISO 9001 standards.
Superior Chemical Resistance: Excellent resistance to acids, alkalis, and hydrocarbons found in aggressive leachate.
Enhanced Slope Stability: Textured HDPE surfaces are available to increase friction angles for steep side slopes.
Cost-Effective Installation: Wide-width rolls (up to 8m) reduce the number of field seams, saving labor and welding consumables.
