High-Strength Composite Geomembrane
A multi-functional anti-seepage solution engineered for large-scale hydraulic and civil engineering projects, combining superior performance with reliable construction efficiency.
Product Overview
Composite Geomembrane is a high-performance geosynthetic material manufactured through calendering and hot-melt coating processes. It consists of geotextiles (or glass fiber mesh) as the water-conducting layer and polymer materials (PE film, EVA) as the anti-seepage layer. This innovative design integrates multiple functions including anti-seepage, protection, reinforcement, drainage, and isolation in a single material.
Key Performance Features
- Excellent anti-seepage and waterproof performance for effective water penetration prevention
- Superior elasticity and deformation adaptability to accommodate foundation settlement
- High resistance to aging and chemical corrosion for harsh environmental conditions
- Wide operating temperature range with extended service life
- Reduced long-term maintenance and replacement costs
- Enhanced toughness exceeding single-layer cloth or film performance
Applications
Earth-rock dams & rock-fill dams
Masonry dams & roller-compacted concrete dams
Channels & liquid storage pools
Waterproof layers for expansive soil and collapsible loess
Construction cofferdams & anti-seepage linings
Subways, basements, and tunnels
Roadbed foundation salinization prevention
Tailings dams & sewage reservoir dams
Waste yards & reservoir areas
Roof and basement anti-seepage and moisture-proof
Horizontal anti-seepage blankets for dikes and dams
Vertical anti-seepage layers for foundations
Laying Method Guidelines
Edge welding seam lap width: 80-100mm with clean, dry joints free of contaminants
Proper alignment of PE single films at joints with consistent lap width and smooth surface
