Product Description
Two Fabrics and One Film Composite Geomembrane
High-strength composite geomembrane featuring two layers of geotechnical fabric and one layer of plastic film, designed for demanding civil engineering applications with thickness options from 0.2mm to 3mm.
Product Overview
Composite geomembranes are engineered impermeable materials that combine plastic films with non-woven geotextiles. These specialized materials provide superior seepage prevention and structural reinforcement for critical infrastructure projects.
Key Applications
- Channel Seepage Prevention: Excellent impermeability performance for water conveyance systems
- Landfill Liners: Effective containment of leachate to protect groundwater and environment
- Artificial Lakes & Underground Projects: Weather-resistant and durable waterproofing solutions
Structural Configuration
Available in two primary configurations:
- One Fabric One Film: Single geotextile layer with plastic film
- Two Fabrics One Film: Enhanced strength and durability with dual geotextile layers
Installation Methods
- Burial Method: Embed in soil with sand cover and compaction
- Welding Method: Thermal fusion or extrusion welding for seamless connections
Performance Advantages
- High Strength: Superior tensile strength and tear resistance
- Extended Lifespan: 50-70 year service life under normal conditions
- Environmental Protection: Ideal for eco-sensitive applications including landfills and water containment
