Product Overview

Geosynthetic Clay Liner with HDPE Geomembrane is a composite waterproofing material that combines bentonite geosynthetic clay liner (GCL) with high-density polyethylene (HDPE) geomembrane. This product combines the excellent impermeability of bentonite with the strength, durability, and resistance to UV, chemicals, and environmental stress of HDPE geomembrane. It provides an efficient and cost-effective solution for waterproofing applications in various challenging environments, such as landfills, artificial lakes, and water containment projects.

Product Features

• Superior Waterproofing Performance: The bentonite in the GCL expands when hydrated, effectively preventing water penetration.
• High Strength and Durability: The HDPE geomembrane offers additional mechanical strength, allowing the material to withstand high pressure and stress.
• Chemical Resistance: HDPE provides excellent resistance to chemicals, including wastewater and contaminants, ensuring long-term performance.
• Eco-friendly: Made with recyclable materials, the product meets modern environmental standards.
• UV Resistance: The HDPE geomembrane resists degradation from UV exposure, ensuring longevity even under harsh sun conditions.

Product Specifications

• Composition: Composed of a bentonite geosynthetic clay liner (GCL) and an HDPE geomembrane.
• Thickness: GCL thickness typically ranges from 5mm to 10mm, while the HDPE geomembrane thickness ranges from 0.5mm to 2mm (customizable based on project requirements).
• Width: Maximum width up to 8 meters to meet various project needs.
• Tensile Strength: HDPE geomembrane typically has a tensile strength of 20-30 MPa for superior mechanical strength.
• Permeability: The GCL has a permeability coefficient of typically 10^-9 cm/s, providing excellent waterproofing capabilities.

Applications

• Landfills: Ideal for landfill liners, preventing harmful leachate from contaminating groundwater.
• Artificial Lakes: Used for waterproofing in artificial lakes, ponds, and reservoirs to prevent water leakage.
• Mining Tailings: Suitable for tailings dams and mining operations to prevent contamination of surrounding land and water.
• Soil Remediation: Used for soil containment, preventing harmful substances from spreading to surrounding areas.
• Water Conservancy Projects: Applied in reservoirs, canals, and other water management projects for long-term leak protection.
• Underground Projects: Provides waterproofing in underground structures such as parking lots, subways, and tunnels.

Construction Recommendations

1. Subgrade Preparation: Prior to installation, ensure that the base is free of sharp objects, debris, and irregularities that could damage the geomembrane. The surface should be smooth and uniform.

2. Installation Method: Lay the Geosynthetic Clay Liner with HDPE Geomembrane in an orderly fashion to minimize overlapping seams. Pay close attention to the proper sealing of seams.

3. Seam Welding: Use specialized welding equipment to properly join seams, ensuring that the welds are strong and impermeable. Thermal welding or extrusion welding techniques are recommended.

4. Protection Against Damage: During installation, take care to avoid damage to the membrane. Ensure that there is no excessive friction or mechanical force that could tear the membrane.

5. Covering and Protection: After installation, it may be necessary to cover the membrane to protect it from UV radiation, extreme weather, or mechanical damage.

6. Quality Control: After installation, perform thorough quality checks to ensure all performance parameters meet design specifications and that no leakage occurs.
