Geocomposite Membrane and Impervious Geotextile with 1G1M and 2G1M Configuration

Product Specification

Introduction: Unmatched Performance Through Advanced Composite Technology
GeoComposite Pro represents the pinnacle of geosynthetic engineering, combining geotextiles and geomembranes into a single, high-performance product. Available in both one-geotextile-one-membrane (1G1M) and two-geotextiles-one-membrane (2G1M) configurations, this composite membrane delivers multiple critical functions—separation, filtration, drainage, and waterproofing—in one easy-to-install solution. Ideal for environmental containment, water conservation, and civil engineering projects requiring reliable, multi-functional performance.

What is Geocomposite Membrane?
A geocomposite membrane is manufactured by thermally bonding a high-density polyethylene (HDPE) geomembrane to one or two layers of non-woven geotextile. This creates a robust, integrated system where each component serves a specific purpose:

• Geomembrane Core: Provides excellent impermeability and chemical resistance

• Geotextile Layer(s): Offer superior filtration, drainage, and protection capabilities

• Composite Structure: Ensures optimal performance while simplifying installation

Key Advantages: Multi-Functional Efficiency

1. Comprehensive All-in-One Solution
GeoComposite Pro eliminates the need for separate material sourcing and installation. The pre-engineered composite delivers multiple functions simultaneously:

• Effective separation of dissimilar materials

• Efficient cross-plane drainage

• Reliable fluid containment

• Superior puncture protection

2. Enhanced Mechanical Performance
The composite structure delivers exceptional physical properties:

• High tensile strength (≥20 kN/m)

• Excellent puncture and tear resistance

• Outstanding interface friction characteristics

• Maintains integrity under heavy loads

3. Superior Hydraulic Performance

• Extremely low permeability coefficient (≤1.0×10⁻¹³ cm/s)

• Excellent drainage capacity through geotextile layers

• Effective filtration prevents soil particle migration

4. Cost and Time Efficiency

• Reduces installation time by up to 50% compared to separate material systems

• Minimizes labor requirements and equipment costs

• Lowers overall project costs through simplified logistics

Product Configurations

One-Geotextile-One-Membrane (1G1M)
Features a single geotextile layer thermally bonded to one side of the geomembrane. Ideal for applications requiring:

• Primary containment with drainage on one side

• Protection of the geomembrane from damage

• Filtration and separation functions

Two-Geotextiles-One-Membrane (2G1M)
Incorporates geotextile layers on both sides of the geomembrane core. Designed for applications requiring:

• Dual-side drainage capabilities

• Enhanced protection for the impermeable core

• Superior interface friction on both surfaces

Applications

Environmental Engineering

• Landfill liners and caps

• Waste containment facilities

• Mining leachate collection systems

• Industrial containment ponds

Water Resources Projects

• Reservoir and canal liners

Installation Guidelines

1. Subgrade Preparation

   • Ensure surface is smooth, compacted, and free of sharp objects

   • Verify proper slope gradients for drainage

2. Panel Deployment

   • Unroll panels with geotextile side facing soil/aggregate

   • Maintain minimum 150mm side overlaps

   • Ensure proper orientation for drainage requirements

3. Seaming and Connection

   • Use thermal fusion welding for geomembrane seams

   • Overlap geotextile layers appropriately

   • Conduct quality testing on all seams

4. Protection and Backfilling
