In recent years, China's construction waterproofing industry has witnessed a transformative shift from traditional asphalt-based materials to advanced polymer materials. Three representative polymer waterproofing membranes—PVC (Polyvinyl Chloride), TPO (Thermoplastic Polyolefin), and HDPE (High-Density Polyethylene)—are becoming the preferred solution for modern construction waterproofing due to their exceptional performance. This article provides an in-depth analysis of the characteristics and applications of these three materials and highlights the innovative achievements of industry leader Canlon in the polymer sector.
Part 1: Performance Comparison: Technical Characteristics of the Three Polymer Materials
1. PVC (Polyvinyl Chloride) Membranes
Core Advantages: Balanced comprehensive performance, cost-effectiveness, excellent flame retardancy.
Material Properties: Flexibility adjusted with plasticizers, strong chemical corrosion resistance, seams formed into an integrated waterproof layer through heat welding.
Applications: Suitable for industrial plants, large public building roofs, and underground projects, especially for cost-sensitive projects requiring durable waterproofing.
2. TPO (Thermoplastic Polyolefin) Membranes
Core Advantages: Eco-friendly, plasticizer-free, exceptional weatherability, significant energy-saving effects.
Material Properties: No plasticizer migration or aging risks; white surface reflectivity exceeds 80%, reducing building energy consumption; excellent ozone and UV resistance.
Applications: Photovoltaic roofs, green roofs, public buildings and medical facilities with high environmental requirements.
3. HDPE (High-Density Polyethylene) Membranes
Core Advantages: High mechanical strength, ideal for pre-applied bonded technology.
Material Properties: Tear resistance exceeding 600N/mm, strong chemical corrosion resistance; pre-applied bonded structure forms permanent adhesion with cast-in-place concrete, eliminating water migration risks.
Applications: Underground projects, tunnels, utility tunnels, landfills, and other projects requiring high material strength.
Part 2: Application Evolution: From Single Materials to System Solutions
Modern waterproofing engineering has evolved from mere material supply to systematic services. An excellent polymer waterproofing system should include:
Customized Materials: Formula adjustments based on climate zones and project areas.
Professional Accessories: Matched construction tools, fittings, and auxiliary materials.
Standardized Processes: Established standardized procedures from substrate preparation to detail joints.
Systematic Maintenance: Full lifecycle quality tracking services.
Part 3: Industry Benchmark: Canlon's Path to Polymer Innovation

Hong Kong-Zhuhai-Macao Bridge Artificial Island: PVC salt corrosion-resistant waterproofing system.
Part 4: Development Trends: Integration of Green and Intelligent Technologies
Future polymer waterproofing materials will exhibit three major trends:
Green Raw Materials: Develop bio-based polyolefins to reduce petroleum dependency.
Intelligent Manufacturing: Introduce Industry 4.0 production lines for full-process quality traceability.
Mechanized Construction: Promote automatic welding robots to improve construction precision.
Conclusion
The widespread adoption of polymer waterproofing materials marks the entry of China's construction waterproofing industry into a new "performance-driven" stage. The three material systems represented by PVC, TPO, and HDPE, combined with systematic solutions provided by leading enterprises like Canlon, are reshaping the industry ecosystem. Choosing the right polymer waterproofing system is not just about selecting materials but also about ensuring building safety for decades to come.
