Product Description
Double-Membrane Single-Fabric Composite Geomembrane
Advanced geotechnical material combining two geomembrane layers with geotechnical fabric for superior environmental protection applications.
Product Overview
This composite geomembrane features a unique structural design with two layers of geomembrane sandwiching a layer of geotechnical fabric. This configuration delivers exceptional impermeability while enhancing tensile strength and extensibility for superior adaptability and durability in demanding environmental conditions.
Key Features & Benefits
- Superior Impermeability: Dual geomembrane layers ensure excellent water barrier performance and prevent seepage
- Enhanced Structural Strength: Geotechnical fabric reinforcement provides increased tensile strength and stability under load
- Excellent Flexibility: Adapts to various terrain conditions and foundation surface changes
- Long-Term Durability: High molecular materials with anti-aging agents ensure extended service life in diverse environments
Applications
- Water Conservancy Projects: Reservoirs, artificial lakes, and river channel seepage control
- Municipal Engineering: Landfill impervious construction and wastewater treatment facilities
- Transportation Infrastructure: Road and railway subgrade reinforcement and drainage systems
- Environmental Protection: Polluted soil remediation and solid waste covering applications
Construction Guidelines
- Edge welding bead lap width: 80mm-100mm
- Ensure joint areas are free from dirt, moisture, and dust contaminants
- Adjust geomembrane alignment before welding to maintain proper width and eliminate creases
- Refer to detailed geomembrane construction scheme for comprehensive installation procedures
