How to Maintain GRC? A Comprehensive Analysis of Daily Maintenance Strategies and Key Points for GRC Systems

The enduring blossoming of architectural aesthetics relies on the utmost care of every detail. As a new building material combining both decorative and structural functions, GRC (glass fiber reinforced concrete) shines in grand theaters, commercial complexes, landmark buildings and other settings with its lightweight, high-strength and flexible formability. However, to ensure a service life of more than 20 years along with lasting beauty, scientific and systematic daily maintenance is essential. With 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials and based on over a thousand engineering projects, Qinglong Group has developed a set of highly effective GRC system maintenance strategies, providing professional guidance for designers and owners.

The Core Logic of GRC Maintenance: From Material Properties to Full Life-Cycle Management

GRC material is composed of cement-based composite and glass fibers, and its maintenance must take into account both the durability of concrete and the characteristics of composite materials. While participating in the formulation of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong Group found that more than 60% of GRC damage stems from improper initial maintenance. Therefore, maintenance work should span the entire life cycle from installation acceptance through the service period: after installation, a 7-14 day curing period is required to ensure stable material strength; during daily use, a regular inspection mechanism should be established, focusing on joint sealing, surface coatings, and the condition of anchoring systems. These three key aspects together constitute the 'golden triangle' of GRC maintenance.

Key Points of Daily Maintenance: Practical Application of the Three-Level Protection System

Level-one protection focuses on surface cleaning and coating protection. The organic coating on the GRC surface is the first barrier against ultraviolet rays and acid rain erosion. Qinglong's technical team recommends that, depending on the service environment, coating inspections be carried out every 2-3 years in coastal areas and every 3-5 years in inland areas, using professional neutral cleaning agents to remove surface stains, and avoiding direct high-pressure water jets that could cause coating peeling. For areas with localized chalking, timely local repair is required, using fluorocarbon or silicone-acrylic coatings with good compatibility with the original coating to ensure color consistency.

Level-two protection concerns structural safety testing. As a National High-Tech Enterprise, Qinglong has established an industry-leading structural health monitoring standard: annual torque testing of the anchoring systems of GRC components to ensure that bolt tightening force meets design requirements, and ultrasonic flaw detection every 3 years to check the internal fiber distribution, with particular attention to stress concentration areas such as cantilevered components and irregular nodes. In the Century Plaza renovation project on Nanjing East Road, Qinglong used BIM technology to establish digital maintenance archives, achieving real-time monitoring of the deformation of translucent GRC components and providing replicable experience for similar projects.

Level-three protection strengthens response strategies for special environments. For extreme climate conditions, Qinglong's R&D center provides customized solutions: in cold regions, snow on component surfaces must be cleared in winter to prevent freeze-thaw cycles from damaging the internal structure; in high-humidity environments, additional ventilation structures are recommended to reduce the risk of condensation corroding GRC. In a landmark project in Malaysia, Qinglong embedded humidity sensors inside GRC components and optimized maintenance cycles based on local climate data, enabling the project to maintain a 15-year maintenance-free record in a tropical rainy environment.

The Value of Professional Maintenance: From Cost Control to Asset Appreciation

Scientific GRC maintenance not only extends the service life of the material but also creates significant economic value. According to Qinglong's enterprise service data, systematic maintenance can extend the life of GRC components by more than 50% and reduce full life-cycle costs by 30%. For developers, a well-maintained condition can enhance the valuation of building assets; for designers, a consistently beautiful GRC finish is the continuation and presentation of the design concept. As the vice president unit of the China GRC Association, Qinglong has always advocated the philosophy of 'prevention first, precise maintenance,' offering one-stop solutions from material selection to lifelong maintenance through full-chain services covering detailed design, manufacturing, construction and installation, and after-sales maintenance.

Architecture is frozen art, and maintenance is the guardian that keeps that art forever alive. With 28 years of professional expertise, Qinglong Group integrates its commitment to 'meticulousness and the constant pursuit of excellence' into every maintenance detail, not only safeguarding GRC materials but also contributing to the sustainable development of urban architecture. Choose professional maintenance, and let every GRC decoration become an aesthetic symbol that stands the test of time.
