Product Description

Composite Geomembrane for Impermeability & Reinforcement

Professional geosynthetic membrane combining plastic film impermeability with non-woven fabric reinforcement for environmental protection and civil engineering applications.

Product Overview

Composite geomembranes are engineered impermeable materials manufactured by combining plastic films as the base impermeable layer with non-woven geotextile fabrics. The impermeability primarily depends on the plastic film component, while the non-woven fabric provides reinforcement and protection.

Key Properties & Benefits

High-density polyethylene (PE) construction for superior chemical resistance
Excellent flexibility and adaptability to ground deformation
Low-temperature resistance and frost protection capabilities
Combines isolation, drainage, reinforcement, protection, and sealing functions
Strong extensibility with nominal fracture strength from 2.50 to 20 KN/m

Primary Applications

Earth-rock dams, rockfill dams, and roller compacted concrete dams
Channel lining and liquid storage containment systems
Subway, basement, and tunnel waterproofing layers
Roadbed foundation protection and saline control
Tailings dams, reservoirs, and waste treatment facilities
Expansive soil and collapsible loess waterproofing

Installation Guidelines

Edge welding bead lap width: 80-100mm
Ensure juncture areas are clean, dry, and free of contaminants
Align geomembrane edges properly before welding to maintain consistent width
Avoid creases and ensure smooth surface during installation
Refer to detailed geomembrane construction scheme for specific project requirements
