Analysis of Causes and Preventive Measures for Honeycomb and Pitted Surfaces on GRC Components After Installation

The refined presentation of architectural decoration depends on perfect control of every detail. As an industry leader with 28 years of experience in detailed design, manufacturing, construction and installation, and after-sales maintenance of UHPC/GRC/GRG/GRP materials, Qinglong has always upheld an attitude of "meticulousness and constant improvement," providing designers and owners with full-chain, expert-level solutions. Today, we focus on the common honeycomb and pitted surface problems of GRC components after installation, presenting a professional, in-depth technical analysis from cause analysis to preventive measures.

Tracing the Causes of Honeycomb and Pitted Surfaces on GRC Components: The Dual Challenge of Materials and Workmanship

GRC (Glass Fiber Reinforced Concrete), a core category of new architectural decoration materials, has an installation quality that directly affects a building's aesthetics and durability. The formation of honeycomb and pitted surfaces is often the result of the combined effects of material properties and construction workmanship. From a material perspective, an imbalanced mix ratio between glass fibers and the cement matrix, uneven fiber dispersion during mixing, or improper control of concrete slump can easily lead to localized voids after forming; from a workmanship perspective, insufficient vibration during pouring, slurry leakage caused by poorly sealed formwork joints, or surface adhesion caused by improper use of release agents can all trigger honeycomb and pitted surface defects. Qinglong incorporates material performance parameter simulation at the detailed design stage, and through a mix ratio database accumulated over 28 years of engineering practice, can precisely avoid quality risks arising from insufficient material compatibility.

Full-Chain Prevention System: A Quality Closed Loop from Design to Installation

Preventing honeycomb and pitted surfaces on GRC components requires establishing a full-process control system covering detailed design, manufacturing, construction and installation. In the detailed design phase, Qinglong uses BIM technology for component splitting and joint optimization to ensure the tightness of the formwork structure and the rationality of concrete flow paths; in the manufacturing phase, automated mixing equipment and vacuum forming processes are adopted to ensure uniform glass fiber distribution and concrete density, while a "trial production - testing - adjustment" cycle mechanism eliminates material mix ratio deviations in advance; during construction and installation, 3D laser scanning positioning and modular installation standards are strictly implemented, together with customized vibrating tools, to ensure there are no dead zones in concrete pouring. Taking a commercial complex project in Nanning as an example, Qinglong used this system to keep the incidence rate of honeycomb and pitted surfaces on GRC components below 0.5%, far below the industry average.

Industry Benchmark Practices: Qinglong's Technological Innovation and Standards Leadership

As a participating unit in drafting the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings (JGJ/T423-2018), Qinglong has deeply integrated the standard's requirements into the entire production and construction process. Targeting the characteristics of GRC materials, the company's R&D center has developed a "real-time fiber dispersion monitoring system" and a "dynamic concrete fluidity adjustment technology," improving material homogeneity at the source; in installation workmanship, Qinglong pioneered the dual-stage "pre-assembly - on-site fine adjustment" construction method, identifying and correcting potential defects through factory pre-assembly and combining on-site 3D positioning technology to achieve precise installation. These innovative practices not only guarantee project quality but also drive the upgrading of industry technical standards, demonstrating the technical strength of a national high-tech enterprise.

From material R&D to project delivery, Qinglong has always taken "creating beautiful architecture" as its mission, transforming 28 years of full-chain experience into the capability to solve industry pain points. When facing quality problems such as honeycomb and pitted surfaces on GRC components, only with professional technical support and refined management as safeguards can the unity of aesthetics and function in architectural decoration be achieved. Going forward, Qinglong will continue to deepen its expertise in the UHPC/GRC/GRG/GRP materials field, provide better products and services for construction projects worldwide, and work hand in hand with partners to reach new heights in the industry.
