Polyvinyl Chloride (PVC) Waterproof Roll – High-Strength Flexible Polymer Membrane for Roofs and Foundations

Younson Polyvinyl Chloride (PVC) Waterproof Roll is made from PVC resin as the main material, with added plasticizers, stabilizers, antioxidants, and anti-aging agents. The material features high strength, high elongation, excellent flexibility, and can be used exposed or unexposed, with some types also providing root resistance.

Scope of Application

• Mainly used for roofs, basements, civil defense projects, utility tunnels, subways, grain storage, and landfill projects.
  

Product Features

• High tensile strength and elongation, low shrinkage, excellent dimensional stability.
  
• Excellent aging resistance, chemical resistance, and root-puncture resistance.
  
• Good weldability, with heat-welded seams integrating fully with the substrate; no delamination at overlaps.
  
• Good water vapor permeability, allowing condensation to escape.
  
• Excellent flexibility at high and low temperatures, suitable for environments with wide temperature variations.
  
• Made with environmentally friendly materials, non-polluting, with long service life.
  

Executive Standards

• GB 12952-2011 《Polyvinyl Chloride (PVC) Waterproof Roll Materials》
  
• Root-resistant rolls meet all exposed roll requirements of GB 12952-2011 and GB/T 35468-2017 《Root-Resistant Waterproof Rolls for Green Roofs》
  

Construction Methods

• Mechanical Welding: Use welding machines for large-area installation; fast construction.
  
• Manual Welding: Use handheld welding guns for small areas or details. Manual welding includes three steps:
  
  1. Spot welding: Fix roll position; lightly heat and press.
     
  2. Pre-welding: Seal edges to prevent heat dissipation.
     
  3. Final welding: Fully join two rolls into one.
     
• Cold Adhesion: Use compatible adhesive for full or partial bonding; weld overlap edges tightly.
  
• Mechanical Fastening: Secure rolls to the substrate with mechanical fasteners; weld overlaps to ensure seal.
  

Transportation and Storage

• Store different types and specifications separately; do not mix.
  
• Avoid direct sunlight and rain; ensure ventilation.
  
• Maximum storage temperature: 45℃; store flat, stacking height ≤5 layers; vertical storage in single layers.
  
• Keep away from acids, alkalis, oils, and organic solvents.
  

Prevent tilting or compression during transport; cover if necessary.
