Short Composite Geomembrane
Product Overview
Composite geomembrane is an impermeable material formed by laminating geotextile with geomembrane, primarily used for seepage prevention and isolation. It is available in various structural configurations, including one geotextile/one geomembrane (1G1M), two geotextiles/one geomembrane (2G1M), and three geotextiles/two geomembranes (3G2M). Manufactured using polymer materials and anti-aging additives, it remains functional under extreme temperature conditions.
Performance Characteristics
High tensile, tear, and puncture resistance
Excellent strength with high elongation capacity and deformation modulus
Resistant to acids, alkalis, corrosion, and aging
Combines the impermeability of geomembranes with the reinforcement, protection, and filtration functions of geotextiles
