Exceptional Flexibility: The inherent flexibility of PVC allows it to conform well to uneven subgrades, adapting to ground settlement and deformation without brittle failure.
High Puncture Resistance: The 1.0mm thickness provides good mechanical strength, effectively resisting penetration from underlying sharp gravel or root penetration.
Superior Impermeability: Features an extremely low water vapor transmission rate (typically <1.0 x 10⁻¹³ cm/s), forming a complete and reliable hydraulic barrier.
Good Chemical Resistance: Resists a wide range of acids, alkalis, and salts, making it suitable for containing wastewater and landfill leachate in various complex environments.
Excellent Weldability: Seams are made using hot wedge or hot air welding, resulting in high seam strength (typically ≥ 80% of the parent material strength). This allows for efficient installation, reliable seam quality, and easy testing.
Weather & UV Resistance: The inclusion of UV stabilizers in the formulation allows for exposed outdoor use for specified durations without significant performance degradation.
High Elongation at Break: The fracture elongation of 40 mil (1 mm) PVC geomembrane can usually reach 200% to 300%, which means it can withstand large tensile deformation without breaking, reflecting its excellent deformation adaptability.
