How to Renovate GRC Exterior Walls in Fuling: Construction Process for Replacing Lightweight GRC Curtain Wall Panels

How to Renovate GRC Exterior Walls in Fuling: A Complete Breakdown of the Lightweight GRC Curtain Wall Panel Replacement Construction Process

In existing building renewal projects in Fuling, GRC exterior walls, long exposed to the rainy, high-humidity environment and temperature variations of southwest China, are prone to problems such as surface aging, localized cracking, and loosened anchorages. Choosing a renovation solution suited to local conditions can not only restore the aesthetic appeal of the building facade but also fundamentally extend the service life of the exterior wall system. As an industry enterprise with 28 years of full-chain UHPC/GRC/GRG/GRP service experience, Qinglong GRC manufacturer has participated in the implementation of hundreds of GRC exterior wall renovation projects across China. Based on Fuling's local construction conditions and project requirements, we have broken down the complete lightweight GRC curtain wall panel replacement construction process into practical, implementable standard steps, providing useful reference for local owners, builders, and design teams.

I. Core Survey Preparation Before GRC Exterior Wall Renovation in Fuling

Before officially starting GRC exterior wall renovation work in Fuling, targeted on-site surveys must be completed—this is the core prerequisite for avoiding safety hazards and cost overruns in subsequent construction. First, conduct a comprehensive inspection of the base anchoring system of the original GRC curtain wall panels, focusing on the corrosion of expansion bolts and the load-bearing capacity of hangers. At the same time, taking into account Fuling's climate features—frequent rainstorms in summer and low-temperature freeze-thaw cycles in winter—test the flexural strength and surface adhesion of the original GRC panels, and mark and record areas showing chalking or hollowing to avoid missing hidden damage. Second, confirm the parameter requirements for the lightweight GRC curtain wall panels after renovation based on the building's original design needs: the standard GRC curtain wall panels produced by Qinglong GRC manufacturer weigh only 1/4 of natural stone, requiring no additional reinforcement of the existing building structure, making them highly suitable for the renovation scenarios of most existing buildings in Fuling. Meanwhile, different surface treatment effects such as stone-look, matte, and textured finishes can be selected according to the architectural style, balancing aesthetics and weather resistance.

II. Standardized Construction Process for Lightweight GRC Curtain Wall Panel Replacement

The core step of GRC exterior wall renovation in Fuling is the replacement of lightweight GRC curtain wall panels. The standardized construction process can be divided into four core steps: First, removal of old panels—the construction team should adopt sectional demolition to avoid vibration damage to surrounding intact GRC panels caused by large-scale demolition. During removal, residual mortar and loose anchorages on the base should be cleaned simultaneously, and base areas with insufficient strength should be re-leveled. Second, positioning and setting out—using 3D laser scanning positioning technology, the installation datum points for new panels are determined according to pre-detailed layout drawings, ensuring the gap deviation between panels is controlled within 2mm to prevent misalignment during assembly. Third, installation of new panels—Qinglong GRC curtain wall panels adopt a modular dry-hanging process, with each panel connected to the base through dedicated stainless steel hangers, and anchoring nodes treated with double anti-loosening measures, technically eliminating the risk of later panel detachment. Fourth, joint treatment and surface protection—panel joints are filled with neutral silicone weatherproof sealant, and after completion, a hydrophobic coating is sprayed over the entire exterior wall to further enhance the water impermeability of the GRC panels, adapting to Fuling's rainy climate.

III. Pitfall-Avoidance Points and Quality Assurance for GRC Exterior Wall Renovation in Fuling

Many local project parties in Fuling easily fall into the misconception of "only looking at panel prices while ignoring full-process services" when carrying out GRC exterior wall renovation. In fact, construction precision and after-sales support are what truly determine the final result. Qinglong, as an industry organization that participated in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), JGJ/T423-2018, holds a Grade II qualification for professional curtain wall engineering contracting. For GRC exterior wall renovation projects in Fuling, it provides one-stop services ranging from preliminary on-site surveys, detailed design, and customized production to on-site installation and 5-year after-sales maintenance, avoiding the problem of responsibility shirking in multi-party coordination. Also note that when selecting GRC panels, be sure to rely on test reports from reputable manufacturers. High-quality GRC panels have a bending strength of over 20MPa, far exceeding ordinary inferior products, enabling them to better withstand Fuling's extreme weather changes and reduce later maintenance costs.
