Cause Analysis and Solutions for Honeycomb and Pitted Surfaces on GRC Components After Installation

The refined presentation of architectural decoration depends on precise control of every detail. In the application of GRC components, honeycombing and pitted surfaces, as common issues affecting appearance and durability, have long been a focus of industry attention. Qinglong Group, an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, leverages its full-chain service experience to thoroughly analyze the causes of and solutions to this problem, providing professional solutions for designers and owners.

Core Causes of Honeycombing and Pitted Surfaces in GRC Components

The occurrence of honeycombing and pitted surfaces in GRC components is essentially the result of an imbalance between material properties and construction techniques. From a material perspective, the mix design of glass fiber reinforced concrete is particularly critical: insufficient fluidity of the cement paste or uneven dispersion of glass fibers can easily trap air bubbles. During production, improper mold surface treatment or non-standardized vibration techniques can create holes and depressions on the component surface. During the construction and installation stage, incomplete substrate preparation or poorly sealed joints may also lead to later surface defects. Qinglong Group uses BIM technology at the detailed design stage to simulate material flow paths, avoiding potential risks at the source.

Full-Process Control: A Systematic Solution to GRC Quality Issues

Solving GRC honeycombing and pitting requires a full-chain quality control system. In the manufacturing stage, Qinglong adopts automated mixing and vacuum casting processes to ensure uniform blending of cement-based materials and glass fibers, combined with high-frequency vibrating tables to eliminate air bubbles; high-precision steel molds and eco-friendly release agents are selected to guarantee surface smoothness. During construction and installation, 3D laser scanning technology is used for precise positioning, combined with Qinglong's patented anchoring system (Patent No.: ZLXXXXXX) to achieve seamless joining. In the after-sales maintenance stage, defect repair services with 24-hour response are provided, using specialized repair materials to restore component integrity.

Industry Experience Empowerment: A Commitment to Quality from Projects to Standards

As a participating unit in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong Group has transformed 28 years of engineering practice into standardized solutions. In the Dongguan Women and Children's Activity Center project, optimizing the GRC mix and casting processes achieved nearly 6,000 square meters of special-shaped components with zero honeycombing or pitting. In the Century Plaza renovation project on Nanjing East Road, a UHPC-GRC composite system was adopted, ensuring both shape precision and enhanced durability. These practices attest to Qinglong's quality commitment of 'meticulousness and excellence.'

In the face of quality challenges with GRC components, choosing a supplier with full-chain service capabilities is essential. With its strength as a national high-tech enterprise, Qinglong Group integrates detailed design, manufacturing, construction and installation, and after-sales maintenance into one-stop services, providing full-cycle assurance for architectural decoration projects from concept to completion. As advocated by Qinglong's mission of 'Creating Aesthetic Architecture,' only by deeply integrating professional technology with craftsmanship can every GRC component become a vivid interpretation of architectural aesthetics.
