Product Overview
High-Performance Polyvinyl Chloride Waterproofing
PVC waterproofing membrane is a premium polymer sheet manufactured from high-quality polyvinyl chloride resin mixed with UV stabilizers and plasticizers. Renowned for its versatility and security, it is the preferred solution for industrial roofing, reservoirs, and underground infrastructure.
As a specialist factory, Tianyuan supplies multiple PVC types including homogeneous (H), fabric-backed (L), and reinforced (P) sheets. With monolithic heat-welded seams and high resistance to environmental stress, our PVC membrane ensures long-term leak protection for global B2B construction projects.
Quick Facts
50-Year Durability
Engineered for long-term protection, with a service life of 20+ years for roofing and up to 50 years for underground use.
Monolithic Seams
Hot-air welded lap joints create a permanent, homogenous bond that is stronger than the membrane itself.
Root Barrier
Excellent resistance to root penetration, making it the top choice for intensive and extensive green roof gardens.
Eco-Friendly Polymer
Flame-retardant and highly recyclable, conforming to modern environmental standards for sustainable construction.
3
Applications
Green Roof Systems
Proven performance as a root barrier for rooftop gardens and planting roof waterproofing.
Hydraulic Engineering
Trusted barrier for reservoirs, artificial lakes, ponds, canals, and water conservancy projects.
Underground Infrastructure
Reliable anti-seepage for basements, subway stations, tunnels, and underground municipal works.
Environmental Protection
Suitable for landfill liners, sewage treatment plants, and industrial anti-pollution engineering.
Transport & Civil Works
Used for bridge deck waterproofing and railway structures to ensure high-durability protection.
4
Key Benefits
High Mechanical Strength
Superior tensile strength and high elongation allow the membrane to adapt to structural deformations.
Excellent Weatherability
Stable performance under extreme UV, ozone, and temperature variations (-25degC to 80degC).
Chemical & Oil Resistance
Strong resistance to a wide range of chemicals, making it adaptable to special industrial waterproofing situations.
Easy Detail Handling
High plasticity ensures fast and secure treatment of corners, edges, and complex architectural penetrations.

Installation Guide
Base Cleaning
Ensure the substrate is smooth, dry, and free from sharp debris, oil, or standing water.
Layout & Spreading
Unroll the PVC membrane smoothly according to the project layout, avoiding wrinkles or tension.
Mechanical Fastening
For roofing, secure the membrane using specialized fasteners and plates along the overlap edge.
Hot-Air Welding
Weld the lap joints using automatic welding equipment at 350degC-500degC for a monolithic seal.
Detail Treatment
Use prefabricated PVC accessories or hand-welding for corners, pipe roots, and drains.
Seam Inspection
Conduct a probe test on all cooled seams to verify continuous watertightness after installation.
