PVC geomembrane is a highly flexible, thermoplastic material used for waterproofing. It is made from a blend of vinyl compounds, plasticizers, and stabilizers, offering exceptional durability and performance for various applications. Known for its exceptional puncture, abrasion, and tear resistance, PVC geomembrane is ideal for preventing contaminants from reaching groundwater and preserving potable water sources. Its broad chemical compatibility makes it a top choice for various buried geomembrane applications.

Indian Standard IS 15909:2020 for PVC Geomembranes

Indian Standard IS 15909:2020 specifies the requirements for Poly Vinyl Chloride (PVC) geomembranes used in lining applications. This standard categorizes PVC geomembranes into two distinct types based on their intended use:

• Category A: This includes PVC geomembranes designed for lining applications in canals, ponds, reservoirs, water features, landfills, hazardous waste management, solid waste management, and industrial effluents. It is also suitable for waterproofing basements, roofs, and terraces.

• Category B: This category covers PVC geomembranes intended for unexposed applications in large underground civil structures such as basements, road underpasses, rail/road tunnels, bunkers, dams, and other significant civil projects. It is also used for waterproofing unexposed roofs and terraces.

By adhering to IS 15909:2020, you ensure that your PVC geomembrane meets industry standards for quality and performance, making it suitable for a wide range of waterproofing and containment applications.
