1. What Is A Polyvinyl Chloride Liner?

A Polyvinyl Chloride (PVC) liner, also known as PVC Geomembrane, is a flexible, impermeable geomembrane made from high-quality PVC resin, designed to prevent water or liquid seepage in containment systems. Manufactured in rolls (3–15 m wide, 10–60 m long) with thicknesses ranging from 0.2 mm to 2.0 mm, Polyvinyl Chloride liners achieve a hydraulic conductivity of <1 x 10⁻¹¹ cm/s, ensuring 99.9% water retention when properly installed (ASTM D7176). These liners are widely used in applications such as aquaculture ponds, irrigation canals, wastewater treatment facilities, and landfill liners, offering a lifespan of 10–20 years in exposed conditions and up to 50 years when buried (Geosynthetic Institute, 2024). Their lightweight nature (0.5–2 kg/m²), ease of welding, and adaptability to complex geometries make them a preferred choice in 20% of global geomembrane applications (Grand View Research, 2024).
