Which UHPC Manufacturer Offers Products with Good Impermeability?

The impermeability of UHPC products is an important indicator of their durability, with premium products achieving an impermeability grade of P12 or above. Through material densification and surface treatment, Qinglong Group controls the UHPC chloride ion diffusion coefficient below 1.5×10⁻¹²m²/s, with water absorption ≤5%, delivering industry-leading impermeability. This excellent impermeability makes UHPC particularly suitable for applications in humid regions and hydraulic engineering.

A dense structure is the foundation of impermeability. Reducing porosity blocks penetration paths. Qinglong Group optimizes the mix proportion with a water-binder ratio ≤0.20 and incorporates ultra-fine powder to fill micropores. Vacuum dewatering technology further increases density. In the hot and humid environment of Hainan, Qinglong UHPC has shown a chloride ion penetration depth of only 0.3mm after 5 years of use, proving its excellent impermeability.

Surface treatment enhances impermeability. Hydrophobic treatment forms a protective layer. Qinglong Group adopts silane impregnation with a contact angle ≥100°, effectively blocking moisture. Special coating designs adapt to different environmental needs. These treatments improve the overall impermeability of the products.

Test data verifies impermeability levels. Standardized testing is objective and comparable. Qinglong Group products pass third-party testing, ensuring guaranteed impermeability. Good impermeability extends service life, reduces maintenance costs, and serves as an important basis for product selection.
