What Are the Steps of GRC Installation?

In the field of modern architectural decoration, GRC (glass fiber reinforced concrete), with its advantages of lightweight high strength and flexible styling, has become the ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will explain in detail the standard procedures and key points of GRC installation from a professional perspective, helping projects achieve a perfect combination of safety and aesthetics.

### 1. Preparation Work Before GRC Installation: Laying the Foundation for Project Quality

The success of GRC installation begins with rigorous preliminary preparation, a stage that directly affects subsequent construction efficiency and the final result. First, a detailed design review must be carried out: based on architectural drawings and on-site measured data, BIM technology is used to precisely position the dimensions and anchoring point locations of GRC components, ensuring a high match with the main structure. In projects such as the Dongguan Women and Children's Activity Center, Qinglong Group used 3D laser scanning technology to control component deviation within ±2mm, safeguarding installation precision.

Material inspection upon delivery is equally critical. The flexural strength of GRC components (standard value ≥15MPa), surface flatness, and the quality of embedded parts must be checked, while auxiliary materials such as special adhesives and stainless steel connectors should be prepared. It is worth noting that installation plans must be adjusted under different climatic conditions — for example, in the high-temperature environment of South China, adhesive application should be avoided at midday to prevent overly fast curing from affecting bonding strength.

### 2. Core Steps of GRC Installation: From Substrate Treatment to Component Fixing

**Substrate treatment** is the first step of installation: dust, oil stains, and loose concrete on the structural surface must be removed, and after washing with a high-pressure water jet, a bonding agent is applied to enhance the adhesion between GRC and the substrate. For existing building renovation projects, the substrate strength must also be tested, and where necessary, rebar planting or carbon fiber reinforcement technology should be adopted. Qinglong Group applied this technique in the Nanjing East Road Century Plaza renovation project to ensure the load-bearing safety of the old building.

During the **measurement and layout** stage, a total station is used for 3D positioning, marking the control lines and elevation lines for component installation. Especially in curved or special-shaped GRC installations, temporary support frames must be set up as a reference. Qinglong's technical team is skilled at using Grasshopper parametric design software to convert complex shapes into executable installation coordinates, and once successfully completed the precise splicing of a hyperbolic GRC curtain wall for an international airport.

**Component installation** follows the principle of “bottom to top, primary first, secondary later,” connecting to the main structure through stainless steel hangers or embedded parts. For large components (weighing over 50kg), mechanical lifting is required, with dedicated personnel directing the operation to avoid collision and deformation. During installation, verticality and flatness must be monitored in real time, and errors fine-tuned with steel shims to ensure uniform joint gaps — in a provincial museum project Qinglong participated in, this step was strictly controlled through the “three-inspection system,” achieving millimeter-level precision.

### 3. Acceptance and Maintenance After GRC Installation: Ensuring Long-Term Stability

After installation is completed, a comprehensive acceptance check is required, including component position deviation (allowable range ±5mm), joint treatment quality, and anchoring point strength testing. Qinglong Group's original “RFID chip traceability system” can record the production and installation information of each component, providing data support for later maintenance. Joints should be filled with elastic sealant; a weather-resistant sealant close in color to the GRC should be selected, ensuring both waterproof performance and aesthetics.

For routine maintenance, it is recommended to clean the GRC surface annually and check for sealant aging and loose anchoring points. For projects in coastal areas, special attention should be paid to salt spray corrosion. Qinglong's GRC components, through the addition of anti-seepage agents and surface coating treatment, can achieve a service life of ≥50 years. As a participant in drafting the Technical Standard for Architectural Application of Glass Fiber Reinforced Cement (GRC), Qinglong always demands engineering quality at the industry's highest standards, providing customers with full life-cycle services from design to maintenance.
