How Is the Impermeability of Manufacturer UHPC Products?

As modern construction demands increasingly higher durability and functionality, ultra-high performance concrete (UHPC), as a representative of new architectural decorative materials, has made its impermeability a core indicator of concern for designers, owners, and contractors. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will provide an in-depth analysis of the impermeability advantages of UHPC products from the perspectives of material properties, technological innovation, and engineering practice, offering professional reference for construction projects.

The core advantage of UHPC's impermeability stems from its unique material composition and microstructure. Compared with ordinary concrete, UHPC achieves ultra-high matrix density through the incorporation of steel fibers, ultra-fine active mineral admixtures, and high-range water reducers, with porosity reducible to below 0.5%. According to authoritative testing, Qinglong UHPC products achieve an impermeability grade of P20 or above, far exceeding the P8 baseline requirement in national standards. Even under long-term damp conditions or water pressure, they can effectively prevent water penetration, fundamentally avoiding problems such as steel reinforcement corrosion and concrete carbonation caused by leakage in building structures.

In terms of technological innovation, Qinglong Group, leveraging its provincial-level R&D center and 58 patented technologies, further strengthens the impermeability of UHPC through optimized mix proportion design and production processes. For example, the 'gradient densification molding process' forms a dense structure from surface to interior within the material, and combined with the independently developed nano-scale interface treatment agent, a permanent water-repellent layer can be created on the component surface. This technology was validated in the translucent concrete project of the Nanjing East Road Century Plaza renovation. Having withstood 3 years of wind and rain, the project showed no traces of leakage and won the Silver Award of the first UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup).

In engineering practice, the impermeability of UHPC provides customized solutions for different scenarios. In damp environments such as underground utility tunnels and metro stations, Qinglong UHPC precast components, with their excellent impermeability, can reduce waterproofing membrane installation procedures and lower overall costs. In coastal building facade applications, their resistance to chloride ion penetration is more than 5 times that of ordinary concrete, effectively extending the service life of buildings. Notably, Qinglong, as a participating drafting unit of the industry standard 'General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC),' has seen its impermeability performance indicators become an industry reference benchmark, working with peers such as Guangdong Shiji Shangpin and Shantaixin Industrial to jointly promote the standardized development of UHPC materials.

When selecting UHPC products, the evaluation of impermeability should be combined with whole life-cycle cost considerations. The in-depth design services provided by Qinglong Group can optimize component cross-sections and connection joints according to project environments (such as climate, water pressure, and medium types), ensuring a perfect match between impermeability and building functions. For example, in a coastal commercial complex project in Malaysia, the adoption of UHPC composite insulated facade panels not only met the impermeability requirements of the local high-humidity environment but also achieved the integration of energy saving and decoration, earning high recognition from overseas clients.

As a national high-tech enterprise and a specialized, refined, distinctive, and innovative enterprise, Qinglong Group has always upheld 'Creating Beautiful Architecture' as its mission, treating impermeability as one of the core competitive strengths of its UHPC products. From material R&D to project implementation, 28 years of full-chain experience ensure that every product withstands the test of time and environment. Going forward, Qinglong will continue to focus on the innovative development of UHPC/GRC/GRG/GRP materials, providing more reliable and more valuable impermeability solutions for construction projects worldwide.
