Superior Impermeability
3-5 layer composite structure achieves <1×10⁻¹⁴ cm/s permeability (10X better than single-layer geomembranes)
Zero-defect manufacturing eliminates pinholes
Enhanced Mechanical Strength
Reinforcing grid layer provides ≥40/35 kN/m tensile strength (MD/XD)
1500N+ puncture resistance for rocky subgrades
Installation Benefits
Pre-fabricated panels reduce field seams by 70%
Cold-weather flexibility (-50°C performance)
Introduction:
Our Multi-Layer Composite Geomembrane is a high-performance barrier solution designed for critical containment applications. By combining multiple functional layers through precision lamination technology, this geomembrane delivers unmatched impermeability, strength, and chemical resistance—outperforming traditional single-layer membranes.
Key Features
1. Multi-Layer Construction
3-5 engineered layers, including:
UV-resistant top film (weatherable)
Reinforcement grid (polyester or fiberglass)
Impermeable core barrier (<1×10⁻¹⁴ cm/s permeability)
Textured/friction-enhanced base (optional)
2. Superior Performance:
Tensile strength: ≥40/35 kN/m (MD/XD) (ASTM D6693)
Puncture resistance: ≥1500N (ASTM D4833)
Chemical resistance (pH 1-14, hydrocarbons, solvents)
3. Installation Advantages:
Pre-fabricated panels (up to 15m wide) minimize seams
Cold-weather flexibility (-50°C to +80°C operational range)
Compatible with all standard welding methods
4. Quality Assurance:
ISO 9001-certified manufacturing
100% spark testing for layer integrity
Third-party validated (SGS, TÜV, FM Global)
