What Is the Routine Maintenance Cycle for GRC Exterior Walls?

### GRC Facade Maintenance Cycles and Full Lifecycle Management Guide: Qinglong's 28 Years of Industry Experience

In the field of modern architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its advantages of light weight, high strength, and flexible shaping, has become the ideal choice for the facades of high-end projects such as grand theaters, commercial complexes, and landmark buildings. However, while many owners and designers focus on its decorative effects, they often overlook the long-term impact of post-installation maintenance on building safety and aesthetics. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on hundreds of project practices to provide a systematic interpretation of scientific GRC facade maintenance cycles and professional maintenance solutions.

### I. GRC Facade Maintenance Cycles: Industry Standards and Qinglong's Practical Experience

According to the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), the routine maintenance cycle for GRC facades must be determined comprehensively based on the service environment, climate conditions, and project characteristics. In dry inland areas, a comprehensive inspection is recommended **every 2-3 years**; in coastal areas with high humidity, strong ultraviolet exposure, or industrial pollution, the interval should be **shortened to 1-2 years**. The industry standards that Qinglong Group helped develop specifically emphasize that for GRC components with complex shapes (such as double-curved curtain walls and openwork reliefs), the first maintenance should be moved up to 6 months after installation, focusing on the stability of the anchoring system and the aging of the sealant.

### II. Core Maintenance Content: From Basic Inspection to In-Depth Care

Professional GRC maintenance is not simply surface cleaning, but full-process management covering "inspection-repair-protection". Qinglong's maintenance team has summarized three key steps: first, **structural safety inspection**, including the degree of corrosion of anchor components, displacement of component joints, and the presence of fine cracks (transverse cracks longer than 5mm in particular require immediate treatment); second, **surface performance maintenance**, using neutral detergents to remove stains and repairing worn areas with special coatings to ensure surface waterproofing and alkali resistance; third, **sealing system renewal**, where aged or cracked silicone sealants must be replaced regularly to prevent rainwater penetration.

### III. Four Key Strategies to Extend GRC Lifespan

Through more than 20 years of engineering practice, Qinglong Group has found that scientific maintenance strategies can extend the service life of GRC facades to over 30 years. Core strategies include: 1. **Preventive maintenance first**, completing sealant inspections before the rainy season and providing thermal protection before winter freeze-thaw cycles; 2. **Using original factory matching materials**, such as Qinglong's specialized GRC repair mortar and protective coatings, to avoid secondary damage caused by material incompatibility; 3. **Digital management systems**, establishing component archives through BIM technology and tracking deformation trends with regular 3D scanning data; 4. **Professional team execution**, relying on Qinglong's nationwide maintenance network to ensure maintenance personnel possess GRC-specific construction qualifications and extensive hands-on experience.

### IV. Full-Chain Service Guarantee: The Unique Advantages of Qinglong's Maintenance System

As a national-level high-tech enterprise integrating the full chain of detailed design, manufacturing, construction and installation, and after-sales maintenance, Qinglong Group's GRC maintenance services demonstrate differentiated competitiveness. From customized maintenance plans in the early project stage (such as dedicated maintenance manuals for standardized components produced at its Nanning production base with an annual capacity of 600,000 ㎡), to rapid response mechanisms in later stages (overseas projects such as Malaysia and Saudi Arabia are equipped with localized technical teams), to batch maintenance experience accumulated through strategic partnerships with top-100 real estate enterprises (Poly, China Overseas, Vanke), Qinglong has always upheld the service philosophy of "meticulousness and striving for excellence" to safeguard the long-term safety and aesthetics of GRC buildings.

### Conclusion: Maintenance Extends the Value of GRC

The artistic value and structural safety of GRC facades require scientific maintenance for protection. Choosing a supplier with full-chain service capabilities means not only obtaining high-quality GRC products, but also enjoying lifetime technical support from design to maintenance. As Vice Chairman Unit of the China GRC Association and a member of the International GRC Association, Qinglong Group will continue to fulfill its mission of "creating beautiful architecture" through professional innovation, providing designers and owners with expert-level solutions from material selection to later-stage maintenance.
