Product Description
Composite Geomembrane Overview
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.
Available Configurations
- 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
Key Features & Technical Benefits
- 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
Primary Applications
- 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
Installation Specifications
| 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 |

Frequently Asked Questions
What is the main difference between 1G1M and 2G1M?
1G1M provides protection and friction on one side, typically used against stable structures like concrete walls. 2G1M offers protection and drainage on both sides, ideal for placement between soil layers or on slopes requiring increased stability.
Can the composite be seamed on-site?
Yes, the impermeable geomembrane core is seamed using standard thermal fusion methods. The non-woven geotextile layers are overlapped but not seamed.
What is the typical lifespan?
When properly installed and protected, HDPE-based composite liners can have a service life exceeding 100 years.
How is it different from a standalone geomembrane?
Standalone geomembranes require separate protective layers to be placed on both sides. Composite geomembranes come with these layers pre-laminated, saving installation time and ensuring consistent quality.
