Product Description
Product Overview
Composite geomembrane is engineered through calendering and hot melt processes, combining one or more layers of geotextiles with polymer materials. The standard configuration features a sandwich structure with 200g geotextiles and 0.5mm polymer film, delivering exceptional strength, durability, and impermeability for demanding engineering applications.
Key Performance Characteristics
- Superior physical mechanical properties for structural integrity
- Excellent environmental resistance including UV protection
- High resistance to hydrolysis across varying humidity conditions
- Temperature adaptability from -40°C to 80°C operational range
- Advanced chemical stability against acids, alkalis, and salts
- Controlled permeability for filtration and drainage requirements
Engineering Applications
- Municipal Construction: Waterproof lining for subways, basements, and tunnels
- Environmental Protection: Landfill anti-seepage systems and containment
- Agricultural Water Conservancy: Irrigation system impermeable pavement
- Transportation Infrastructure: Highway and railway subgrade protection
