Plastomeric Single Ply Membranes

These are resin modified plasticizers produced by calendaring or extruding and are usually non-reinforced but also membranes reinforced with polyester or glass fiber mats/scrim are used.

Example: PVC membranes

PVC membranes are prefabricated sheets of polyvinyl chloride, showing good elongation, tear strength, and puncture resistance. Overlaps are joined by heat fusion or by solvent or chemical adhesives. Design specifications require separation sheets for isolation in between membrane and insulation to prevent migration of chemicals.

PVC waterproofing membranes are used for roofing, underground structures, Tank linings, Tunnel linings, artificial lakes and pond linings.
