What Are the Base Wall Requirements for Installing UHPC Exterior Wall Panels and Analysis of Key Construction Points

Building quality begins with a solid substrate. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group fully understands the decisive role of substrate wall preparation in the installation quality of UHPC exterior wall panels. From detailed design to on-site construction, rigorous control at every stage is the key to achieving a perfect unity of architectural aesthetics and structural safety.

### Core Requirements for the Substrate Wall of UHPC Exterior Wall Panels: Building a Solid Foundation for Installation

UHPC (Ultra-High Performance Concrete), with its ultra-high strength, excellent durability, and design freedom, has become the ideal choice for high-end building facades. Its installation quality depends first on the stability and compatibility of the substrate wall. Drawing on the practice of more than 2,000 projects, Qinglong Group has summarized three core requirements: the substrate wall must reach the design strength grade (e.g., C30 or above), surface flatness deviation must be controlled within ±3mm/2m, and proper moisture-proof and anti-corrosion treatment must be applied. For existing building renovation projects, structural testing is also required to assess the load-bearing capacity of the substrate; where necessary, reinforcement solutions based on Qinglong's patented technology should be adopted to ensure mechanical compatibility with UHPC panels.

The details of substrate treatment directly affect the installation result. Qinglong's technical team emphasizes that the wall surface should undergo interface treatment using a specialized bonding agent to enhance adhesion, along with properly reserved expansion joints and drainage slopes. For different wall types (such as concrete, masonry, and steel structure substrates), Qinglong provides customized substrate treatment solutions—for example, steel structure substrates require additional anti-corrosion coatings and thermal bridge breaks to prevent temperature-induced deformation from causing stress damage to the panels.

### Key Points in UHPC Exterior Wall Panel Installation: Fine-Grained Control Across the Entire Process

As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong Group upholds the philosophy of “meticulous work and the pursuit of excellence” throughout the entire construction process. The survey and layout stage employs 3D laser scanning technology to achieve millimeter-level positioning accuracy; panel installation follows a three-step method of “hoisting–adjusting–fixing,” with adjustable connectors absorbing installation deviations to ensure flush panel joints. In response to the characteristics of UHPC panels, Qinglong has developed a dedicated anchoring system in which a single anchor provides a tensile load capacity of over 15kN—far exceeding industry standards.

Joint treatment is central to both waterproofing and aesthetics. Qinglong adopts a double-sealing process: elastic waterproof rubber strips are filled on the inside, and weather-resistant sealant is applied on the outside, forming a multi-layered waterproof barrier. For curved or specially shaped UHPC components, the 600,000 ㎡ annual production capacity of the production base in Nanning, Guangxi, combined with parametric design and prefabrication, enables rapid on-site installation like “building blocks,” shortening the construction period by 30% compared with traditional methods.

### Qinglong's Full-Chain Services: Expert-Level Support from Design to Maintenance

From the innovative GRC application at the Dongguan Women and Children's Activity Center to the light-transmitting UHPC project at Century Plaza on Nanjing East Road, Qinglong Group draws on 28 years of full-chain experience to provide designers and owners with integrated solutions combining “technology + products + services.” As a contributor to the development of the industry standard Ultra-High Performance Concrete (UHPC) Exterior Wall Panels, Qinglong not only supplies UHPC panels that meet national standards but also uses BIM technology to simulate the entire construction process, proactively mitigating substrate and installation risks.

Choosing Qinglong means choosing full life-cycle assurance, from substrate treatment to after-sales maintenance. Whether for large-scale application in real estate projects or the customized needs of landmark buildings, Qinglong, with its mission of “creating beautiful architecture,” uses professional expertise to solidify every inch of a building's foundation, allowing the aesthetic value and structural safety of UHPC exterior wall panels to endure through time.
