Research on Waterproofing Treatment Technology and Application Strategies for UHPC Curtain Walls in Humid Regions

For building curtain walls in humid environments, waterproofing performance is the key determinant of building quality and durability. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain technical capabilities to provide systematic waterproofing solutions for curtain wall projects in humid regions, from detailed design to after-sales maintenance.

The waterproofing challenge for UHPC curtain walls in humid regions is essentially a complex interplay between material properties and environmental loads. UHPC (Ultra-High Performance Concrete), with its compressive strength exceeding 200MPa and extremely low porosity, inherently possesses an excellent impermeability foundation, but the waterproofing capability of a curtain wall system depends even more on the systematic nature of its structural design. The Qinglong team uses 3D scanning technology to verify the precision of installation substrates, eliminating waterproofing weak points caused by structural deviations at the detailed design stage. This "preventive" design philosophy is precisely the crystallization of 28 years of engineering experience.

From material innovation to structural optimization, Qinglong has built a multi-level waterproofing system. At the material level, a self-developed UHPC-specific interface treatment agent increases the bonding strength of component joints by 40%. At the structural level, an innovative "water-guiding, water-blocking, and water-draining" three-in-one system has been designed: the equal pressure cavity principle balances internal and external air pressure, customized EPDM sealing strips achieve flexible sealing, and concealed drainage channels ensure condensate is discharged in an orderly manner. After a coastal landmark project applied this technology, the curtain wall maintained a zero leakage rate despite three years of typhoon seasons.

Full life-cycle waterproofing protection showcases Qinglong's full-chain advantages of "detailed design + manufacturing + construction and installation + after-sales maintenance". In production, automated casting processes ensure UHPC component surface flatness deviation ≤2mm. During construction, BIM technology is used for pre-assembly simulation to reduce waterproofing damage caused by on-site cutting. In the after-sales stage, digital maintenance records are established, with infrared detection technology providing early warning of potential leakage. This closed-loop management from source control to later-stage monitoring is precisely the technical confidence behind Qinglong's status as a national high-tech enterprise.

As a co-developer of the industry standard "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components", Qinglong has always driven industry progress through technological innovation. In the field of curtain wall waterproofing in humid regions, we not only provide material products, but also deliver systematic solutions that integrate 28 years of engineering wisdom. Whether in the rainy water towns of Jiangnan or in high-humidity coastal cities, Qinglong UHPC curtain walls, with a quality commitment of "meticulous craftsmanship and constant pursuit of excellence", safeguard the lasting safety and aesthetic value of buildings.
