Substrate Wall Requirements and Key Points for UHPC Facade Panel Installation

The refined beauty of architecture begins with precise control of every detail. As a critical prerequisite for UHPC exterior wall panel installation, the quality of base wall treatment directly determines the final decorative effect and structural safety. Drawing on 28 years of experience in detailed design, manufacturing, and construction installation of UHPC/GRC/GRG/GRP materials, Qinglong Group provides an in-depth analysis of the core points of base wall treatment, offering professional solutions for designers and owners.

Basic Requirements for Base Walls of UHPC Exterior Wall Panels

As a new type of architectural decoration material, UHPC (Ultra-High Performance Concrete) imposes stringent standards on the flatness, strength, and stability of base walls. First, the base wall must reach the design strength grade: the surface compressive strength of concrete walls should be no less than 15MPa, and masonry walls require interface treatment to ensure bond strength. Second, wall flatness deviations must be controlled within ±3mm/2m, and verticality deviations must not exceed 5mm/2m, to prevent uneven loading of UHPC panels caused by an uneven base. In addition, the base surface should be clean and dry, free of oil stains, floating dust, and hollowing. For renovation projects of existing buildings, a structural safety assessment of the wall is required, with reinforcement measures taken when necessary.

Key Technical Points of Base Treatment

In the base treatment process, Qinglong Group adopts a full-chain quality control system to ensure that every procedure meets standards. During the interface treatment stage, dedicated interface agents must be selected according to the base material: penetrating interface agents for concrete walls, and flexible interface mortar for autoclaved aerated concrete walls, to enhance the interlocking between the base and the bonding layer. For bases with cracks, epoxy resin injection or polymer mortar repair should be applied; when crack width exceeds 0.3mm, anti-crack mesh fabric must be added. Embedded parts must be installed with three-dimensional positioning, using BIM technology to achieve precise embedding. The tensile load capacity of anchors should be ≥10kN to ensure the long-term safety of UHPC panels.

Environmental Adaptability and Quality Assurance Measures

Different regional climate conditions impose differentiated requirements on base treatment. In humid regions, the base needs a waterproof isolation layer applied with polymer cement waterproof coating, with a dry film thickness ≥1.5mm; in cold regions, the impact of freeze-thaw cycles must be considered, and the moisture content of the base must be controlled below 8%. As a national-level high-tech enterprise with a provincial engineering technology center, Qinglong Group has developed specialized base treatment materials that have passed multiple scientific and technological achievement appraisals and can adapt to extreme environments from -30°C to 70°C. During construction, 3D laser scanning technology is used for real-time monitoring to ensure base treatment precision complies with the requirements of the T/CBMF171-2022 standard "Ultra-High Performance Concrete (UHPC) Exterior Wall Panels."

Full-Chain Services Empowering Project Implementation

As a manufacturer of customized UHPC/GRC/GRG/GRP products, Qinglong Group provides one-stop services from detailed design to after-sales maintenance. During the base treatment stage, the technical team issues specialized plans tailored to project characteristics—for example, for the complex curved base surfaces of landmark buildings, parametric design is combined with modular construction to ensure UHPC panel installation deviations of ≤2mm. By integrating its national network of production bases and offices, Qinglong achieves technical response within 48 hours and has successfully provided base treatment solutions for more than 1,000 major projects at home and abroad, including commercial complexes, museums, and other high-end buildings, fully embodying the corporate mission of "Creating Beautiful Architecture."

Base wall treatment is the cornerstone of UHPC exterior wall panel installation, and its quality directly affects the safety and aesthetics of the building. Supported by 28 years of professional experience, Qinglong Group transforms base treatment into a key link for enhancing project value through technological innovation and strict quality control. Choosing a professional UHPC manufacturer means not only choosing quality materials, but also choosing quality assurance across the entire life cycle.
