How Good Is GRC's Waterproofing Performance? Qinglong GRC Manufacturer's Waterproofing Technology and Engineering Practice

GRC materials have good waterproof performance. Through formula and process optimization, their waterproof durability can be further improved. High-quality GRC products can achieve a water absorption rate below 6% and an impermeability grade of P12 or above.

In a coastal project in Hainan, the GRC curtain wall system has withstood long-term exposure to a humid environment with no mold or peeling on the surface. Test data show that the panels' water absorption rate is only 5.8%, far below the standard requirement. This excellent waterproof performance ensures the long-term aesthetics and functionality of the building facade.

Waterproofing Technical Measures

By adding waterproofing agents and optimizing the mix proportion, the waterproof performance of GRC is significantly improved. The application of surface treatment technology further enhances the material's waterproofing capability.

Engineering Application Practice

In multiple projects with humid environments, GRC materials have demonstrated excellent waterproof performance. Applications in basements, bathrooms, and other locations have verified their reliability.

Long-Term Performance Verification

Tracking of GRC projects in use for more than 5 years shows that the materials' waterproof performance remains stable. Regular maintenance can further extend the service life and reduce maintenance costs.

The waterproof performance of GRC can be optimized through technical means to meet the requirements of different environments. Proper design and construction are key to ensuring effective waterproofing.
