Product Introduction
Composite Geomembrane is a high-performance engineered material combining a durable HDPE geomembrane with a nonwoven geotextile fabric. This dual-layer design offers exceptional hydraulic barrier properties, enhanced puncture resistance, and superior drainage capabilities, making it ideal for projects requiring both containment and filtration. Widely used in environmental, civil, and hydraulic engineering, it ensures long-term reliability in harsh conditions.
Advantages of Composite geomembrane
Dual-Layer Protection
HDPE Layer: Provides impermeability, UV resistance, and chemical stability.
Geotextile Layer: Adds puncture resistance, distributes stress, and facilitates drainage.
High Tensile Strength
Withstands heavy loads and ground settlement without tearing (≥30 kN/m tensile strength).
Easy Installation
Pre-bonded layers eliminate the need for separate geotextile deployment.
Cost Efficiency
Reduces labor and material costs by combining two functions in one product.
Environmental Compliance
NSF/ANSI 61 certified for potable water applications and landfill lining.
Composite Geomembrane Production Process
Material Selection
Virgin HDPE resin + high-strength polyester/polypropylene geotextile.
Lamination
Heat-bonding or needle-punching technology to fuse HDPE and geotextile.
Quality Control
Thickness uniformity checks, peel strength tests (≥6 N/cm), and seam integrity verification.
Rolling & Packaging
Custom widths (2m–10m) and lengths (50m–200m), protected with anti-UV wrapping.
Our product parts of testing equipments:
Thickness Tester Fiber Strength Tester Carbon Black Tester
Product Application
Landfills: Base liners and caps with integrated drainage.
Water Infrastructure: Canals, reservoirs, and wastewater treatment ponds.
Mining: Tailings storage and heap leach pads.
Transportation: Road embankments and railway subgrade stabilization.
Agriculture: Irrigation ponds and biogas digesters.
