PVC Waterproof Membrane is a high-performance thermoplastic polymer waterproof sheet made from PVC resin combined with UV stabilizers, low-temperature plasticizers, aging-resistant additives, and other functional components. It is manufactured through advanced extrusion and calendering processes to create a durable and flexible waterproofing membrane.
With excellent weather resistance, chemical resistance, and mechanical strength, PVC membrane is widely used for exposed roofing systems, underground structures, and special waterproofing projects. The wide 2-meter sheet design reduces the number of joints, while hot-air welding technology creates strong and seamless connections between membrane sheets, effectively eliminating leakage risks caused by traditional adhesive joints.
The membrane can be installed through mechanical fastening, full adhesion, or loose laying methods, providing flexible solutions for different construction conditions. Its high durability, UV resistance, and recyclable thermoplastic properties make it an ideal choice for long-term waterproofing applications.
Key Features & Benefits
When waterproof systems require long-term durability, weather resistance, and reliable joint performance, QINGYUAN PVC Waterproof Membrane provides a high-performance solution for roofs, underground structures, and special waterproofing applications.
Hot-air welded joints create a seamless waterproof layer with strong bonding and eliminate leakage risks caused by membrane separation.
Excellent weather resistance allows long-term outdoor exposure without additional protective layers on suitable roof systems.
Superior temperature resistance maintains stable performance from low temperatures of -25℃ to high temperatures of 120℃.
Strong chemical and corrosion resistance protects structures from acids, alkalis, industrial wastewater, and harsh environments.
Integrated root resistance prevents plant root penetration, making it suitable for green roofs and landscaping projects.
High tensile strength and flexibility adapt to structural movement while reducing cracking and leakage risks.
Breathable structure helps release internal moisture and prevents bubbling or damage caused by trapped vapor.
Multiple installation methods including mechanical fixing, cold bonding, and loose laying provide flexible construction solutions.
Environmentally friendly thermoplastic material can be recycled and supports sustainable green building practices.

Standard Construction Process
Professional installation methods ensure strong welded connections, reliable waterproof protection, and long-term performance for different building applications.
Base Surface Preparation
Clean the substrate by removing dust, debris, and loose materials. Ensure the surface is flat, dry, and suitable for membrane installation.
Membrane Layout & Positioning
Unroll and position the PVC membrane according to the project requirements. Allow the membrane to relax before final fixing.
Mechanical Fixing Installation
Secure the membrane with fixing plates and fasteners along the edges. Ensure stable attachment and strong wind resistance for exposed roof systems.
Cold Bonding Installation
Apply PVC adhesive on suitable substrates and fully bond the membrane to concrete or existing surfaces for underground and renovation projects.
Hot-Air Welding & Detail Treatment
Use hot-air welding equipment to fuse membrane overlaps. Reinforce corners, pipes, drains, and other critical areas with additional PVC layers.
Final Quality Inspection
Inspect welding seams, fixing points, and waterproof details. Conduct water testing after completion to ensure the system is fully sealed.
