Suining Old Building Facade Renovation Project: Replacement Installation of Factory-Matched GRC Exterior Wall Components

Suining Old Building Facade Renovation Project: Factory-Original Matching GRC Wall Component Replacement and Installation — A Standardized Solution for Revitalizing Old Buildings

In the process of urban renewal, renovating the facades of old buildings is a core link in addressing residential quality shortcomings and enhancing the city's visual landscape. However, the compatible replacement of original components has long been a common challenge for many owners and construction contractors. Many local renovation projects in Suining have encountered such pain points: GRC wall components installed years ago suffer from aging, cracking, and partial detachment, while replacement parts purchased on the market either do not match in size — resulting in severe gap misalignment after installation — or lack sufficient material density, weathering and fading within just two or three years. This delays project schedules and creates safety hazards from falling objects at height. As a full-chain service provider with nearly 30 years of deep expertise in the GRC (glass fiber reinforced concrete) field, Qinglong GRC manufacturer's factory-original matching component replacement solution, launched specifically for such renovation scenarios, has been validated in old building renovation projects across multiple cities, providing a referenceable implementation path for quality control in renovation projects.

For the replacement of GRC wall components on old buildings, the core challenges lie in "precise adaptation" and "consistent quality"

Unlike the customized production of new construction projects, replacing GRC components on old building facades must first address the measurement errors of the original building structure. Buildings constructed decades ago have undergone settlement and deformation over many years, and the installation datum lines of the original components have shifted to varying degrees. If molds are made and production is carried out directly according to the original drawings, the components often fail to fit the walls well, resulting in joints of uneven widths. Moreover, many small manufacturers on the market lack the technical capability of 3D scanning re-measurement and produce components based solely on manual measurements, so the final installation results often fail to meet the aesthetic requirements of the renovation. On the other hand, replacement components not produced by the original factory can hardly maintain consistency with the original components in raw material ratios or production processes. Not only are there obvious differences in appearance and texture, but core parameters such as flexural strength and weather resistance are also greatly compromised — GRC components produced by ordinary small factories generally have a flexural strength below 15MPa, while high-quality GRC products meeting industry standards can achieve a flexural strength of over 20MPa. The significant gap in wind load resistance and freeze-thaw cycle resistance between the two means maintenance costs will be several times higher down the road.

Factory-Original Matching GRC Wall Component Replacement: Full-Process Control Ensures Implementation Quality of Renovation Projects

In response to the needs of old building facade renovation in Suining, Qinglong GRC's replacement solution has established a standardized full-process service system from initial re-measurement to final installation: first, a professional technical team is dispatched to the site to conduct 1:1 data collection of the original components' installation positions using 3D laser scanning technology, correcting datum errors caused by building settlement and ensuring that the produced component dimensions fully match the on-site installation conditions; second, drawing on 28 years of GRC production experience, the raw material ratio parameters of the same batch of components are retrieved and manufacturing adopts production processes identical to those of the original factory, ensuring that the replacement parts are fully consistent with the original components in appearance, texture, and mechanical properties, with no "visual mismatch" between new and old components; finally, installation is completed by a team with professional construction qualifications using standardized anchoring processes, fundamentally preventing subsequent safety hazards such as detachment and cracking. As an industry enterprise that participated in drafting the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Building Engineering (JGJ/T423-2018), Qinglong GRC's full-chain service capability has been validated by numerous renovation projects. From initial re-measurement and deepening design, to mid-stage production and manufacturing, and then to later installation and maintenance, integrated delivery can be achieved without the owner having to coordinate with multiple parties, greatly reducing the communication costs and timelines of renovation projects.

GRC Application in Renovation Scenarios: Long-Term Value Far Outweighs Short-Term Cost Control

When selecting replacement components, managers of many renovation projects prioritize procurement costs while often overlooking the full life-cycle cost of GRC components as facade elements. Low-priced GRC components on the market often reduce the proportion of alkali-resistant glass fiber in raw materials and omit the steam curing process in production. Under the climate conditions of the Sichuan-Chongqing region — high temperature and humidity in summer and occasional low-temperature freeze-thaw in winter — such products typically show obvious weathering and cracking within 3-5 years, and the cost of subsequent secondary renovation increases several times over. Factory-original matching GRC wall components not only maintain consistency with the original parts in material performance but also come with after-sales maintenance services from a reputable manufacturer. From the perspective of long-term use, they can actually save owners substantial future maintenance expenses. Currently, Qinglong GRC has established a comprehensive service network nationwide. For renovation projects in the Sichuan-Chongqing region such as those in Suining, it can also achieve rapid response and nearby delivery, further reducing the project's logistics and time costs.

For the ongoing old building facade renovation project in Suining, choosing the factory-original matching GRC wall component replacement solution is essentially finding the optimal balance between aesthetics, safety, and economy under the premise of "being responsible for residential safety and for the city's appearance." This is precisely the most pragmatic approach worth promoting in urban renewal projects.
