Product Description
HDPE Composite Geomembrane
High-performance impermeable material combining plastic film with non-woven fabric for superior tensile strength and puncture resistance in demanding engineering applications.
Product Overview
Composite geomembrane is an impervious engineering material manufactured by combining polyethylene plastic film as the waterproofing layer with non-woven fabric reinforcement. The polyethylene base provides excellent chemical resistance, low-temperature performance, and flexibility while the non-woven fabric enhances mechanical strength and durability.
Key Performance Characteristics
These geomembranes deliver exceptional physical and mechanical properties essential for long-term performance in challenging environments:
High tensile strength with nominal fracture strength up to 20 KN/m
Superior puncture and tear resistance
Excellent chemical and corrosion resistance
Low-temperature flexibility and frost resistance
Adaptability to ground deformation and settlement
Engineering Applications
Earth-rock dams, rockfill dams, and roller compacted concrete dams
Channels, liquid storage pools, mines, and reservoirs
Waterproofing for expansive soil and collapsible loess
Cofferdam construction and seepage control
Subway, basement, and tunnel lining systems
Roadbed foundation saline control
Tailings dams, waste treatment plants, and landfill liners
Roof and basement moisture protection
Horizontal impervious blankets and vertical seepage barriers
Installation Guidelines
For optimal performance, follow these installation requirements:
Edge welding bead lap width: 80mm-100mm
Juncture surfaces must be clean, dry, and free of contaminants
Align geomembrane edges before welding to ensure smooth, wrinkle-free seams
Refer to detailed geomembrane construction schemes for comprehensive installation procedures
