Composite Geomembrane 2.0m-8.0m Width with ≤1.0×10⁻¹² cm/s Permeability for Landfill and Water Containment
High-performance composite geomembrane combining impermeable geomembrane core with protective geotextile layers. Features permeability ≤1.0×10⁻¹² cm/s, friction angles 25°-35°, and 100+ year service life. Available in 1G1M and 2G1M configurations for landfill liners, water reservoirs, mining containment, and civil engineering projects. Certified to ASTM and GRI-GM13 standards.
Composite Geomembrane (Geocomposite) is a high-performance engineered material that combines an impermeable geomembrane core with protective non-woven geotextile layers. This integrated system delivers superior hydraulic barrier protection, mechanical strength, and puncture resistance for demanding civil engineering applications.
- One Geotextile/One Membrane (1G1M): Geomembrane laminated to one geotextile layer, ideal for barrier protection with mechanical reinforcement on one side
- Two Geotextiles/One Membrane (2G1M): Geomembrane sandwiched between two geotextile layers, offering enhanced protection, friction, and drainage on both sides
- Superior Impermeability: Permeability coefficients ≤1.0 × 10⁻¹² cm/s effectively prevent fluid migration
- Enhanced Mechanical Protection: Geotextile layers protect against puncture, abrasion, and installation damage
- Improved Slope Stability: High friction angles (25°-35°) against soils and geosynthetics
- Drainage & Gas Venting: Lateral transmission of liquids and gases reduces pressure buildup
- Chemical & UV Resistance: Excellent durability in harsh environments with service life exceeding 100 years
- Cost Efficiency: Combines barrier, protection, and drainage functions in single installation
- Landfill systems: Base liners, cap liners, leachate collection layers
- Water containment: Reservoirs, ponds, canals, irrigation ditches
- Mining operations: Heap leach pads, tailings dams, secondary containment
- Tunnel waterproofing: Underground structures, basements, foundations
- Transportation infrastructure: Subgrade protection and drainage beneath roads and railways
| Step | Procedure |
|---|---|
| Subgrade Preparation | Foundation must be smooth, compacted, and free of sharp rocks or debris |
| Panel Deployment | Unroll panels across prepared subgrade; for slopes, unroll along contour lines |
| Panel Joining | Dual-track fusion welding for geomembrane core creates continuous leak-proof seams |
| Anchoring & Covering | Secure in anchor trenches and backfill carefully to avoid damage |
| Parameter | Specification |
