PVC Waterproofing Membrane for Roof, Basement and | RFQ Sourcing Details

This PVC waterproofing membrane is intended for waterproofing exposed and non-exposed roofs on steel or concrete structures, as well as basements, foundations, subways and tunnels. Polyvinyl chloride is identified as the main raw material, with additives and anti-aging components incorporated into the formulation.

Available nominal thicknesses include 1.2 mm, 1.5 mm and 2.0 mm. The detailed specification also lists a 1.8 mm option. Standard information identifies a 2.0 m width and 20 m length, while broader roll ranges of 1–2 m wide and 20–50 m long are also stated.

Requested roll dimensions should therefore be confirmed before ordering. The membrane is described as weldable, UV resistant and available in white, gray and other colors.

Three configurations are identified for different project needs: a fleece-backed membrane commonly used for green roofs;a homogeneous, twin-color membrane commonly used for foundations and tunnels;and a polyester-reinforced membrane commonly used for exposed roofs.

Buyers should select the construction according to the substrate, exposure conditions and project design rather than relying on thickness alone. Reported properties include low-temperature foldability at -25°C without cracks and watertightness at 0.3 MPa for two hours.

The also reports dimensional stability, tensile and elongation characteristics, chemical resistance, low- and high-temperature resistance, and self-extinguishing behavior after removal from a fire source.

Because the supplied performance table uses multiple type codes and is labeled inconsistently, buyers should request the test report and exact values for the specific PVC configuration being quoted. Packaging is listed as an inner tube with a PP woven plastic bag, with customized packaging available.

For storage, keep different types and specifications separated;store rolls dry, ventilated and protected from sun and rain;stack them flat no more than five layers high;and prevent tilting or side pressure during transport.

Before procurement, confirm the exact membrane type, reinforcement or backing, nominal thickness and tolerance, roll dimensions, color, seam-welding method, substrate preparation and accessory requirements.

Also request project-specific fire, UV, chemical-resistance and watertightness documentation, plus the applicable inspection standard. Customization and OEM service are stated as available, but the approved specification, packaging, production schedule and inspection plan should be recorded in the purchase agreement.
