Key Considerations for Waterproof Coatings on Construction Sites: The Importance of Strict Standard Compliance

In construction projects, understanding and adhering to relevant waterproof coating standards are crucial. Failure to do so may result in the use of substandard materials or improper application, adversely affecting building quality and safety.​

1. Types of Waterproof Coatings

The Chinese market offers a variety of waterproof coatings, including:​

• Cementitious Capillary Crystalline Waterproof Coatings: These penetrate the substrate, forming crystals that block water ingress.​

• Water-based Asphalt Waterproof Coatings: Utilize asphalt emulsions, known for excellent waterproofing and flexibility.​

• Polyurethane Waterproof Materials: Composed primarily of polyurethane, offering good elasticity, weather resistance, and chemical corrosion resistance.​

• Polyvinyl Chloride (PVC) Waterproof Coatings, Soap-based Waterproof Coatings, Polymer Cement, and Emulsion Waterproof Coatings: Each varies in raw materials and production processes, requiring adherence to specific standards during application.​

2. Production Standards and Quality Control

Each type of waterproof coating must comply with corresponding production standards to ensure quality. For instance, national standards may specify that production lines should have a capacity of no less than 3 million square meters, and manufacturers must possess appropriate qualifications, conduct thorough supervision, and implement quality inspections during production. ​

3. Application and Usage Considerations

The suitability of waterproof coatings depends not only on product quality but also on proper application. Construction personnel should be well-informed about the materials used and strictly follow technical specifications and standards during application to ensure the building's waterproof performance and durability.​

Conclusion

The quality of waterproof coatings directly impacts the long-term stability and safety of structures. Given the variety of waterproof coatings available, each with different raw materials and production processes, it is essential for construction units and purchasers to fully understand relevant standards and technical requirements. Ensuring that purchased and applied products meet these standards is vital for achieving effective waterproofing and preventing structural issues and safety hazards associated with inadequate waterproofing.
