Product Description
HDPE Compound Geotechnical Membrane for Anti-Seepage Solutions
Compound geomembrane is a high-performance geotechnical impervious material manufactured by combining plastic film as the impervious base layer with non-woven fabric reinforcement. The impermeability primarily relies on the plastic film component, while the non-woven fabric provides structural strength and durability.
Key Product Properties
- Exceptional puncture resistance with high friction coefficient
- Superior aging resistance and wide temperature adaptability range
- Excellent drainage resistance and chemical corrosion resistance
- Low density with strong extensibility and deformation adaptability
- Good low-temperature performance and frost resistance
Primary Applications
- Municipal Construction: Impervious lining for subways, basements, and tunnels
- Environmental Protection: Anti-seepage treatment for landfills and containment facilities
- Agricultural Water Conservancy: Anti-seepage pavement for irrigation systems
- Transportation Infrastructure: Highway and railway subgrade anti-seepage treatment
Construction Guidelines
For optimal geomembrane installation, maintain edge welding bead lap width of 80-100mm. Ensure junction areas are free from dirt, moisture, and dust contamination. Adjust both sides of the geomembrane before welding seams to maintain consistent welding width and achieve smooth, crease-free installation. Refer to detailed geomembrane construction schemes for comprehensive installation procedures.
