How to Waterproof UHPC Curtain Walls in Humid Regions? Waterproofing Systems and Qinglong Group Protection Technology

Waterproofing treatment for UHPC curtain walls in humid regions requires building a triple line of defense: "hydrophobic panel surfaces, sealed joints, and cavity drainage". Core measures include silane impregnation of panel surfaces (penetration depth ≥5mm), elastic sealant for joints (movement capability ≥25%), and rear cavity design (drain hole spacing ≤1m). In the Hainan International Convention and Exhibition Center coastal project, Qinglong Group achieved 10 years of leak-free curtain wall performance under an annual rainfall of 2000mm through whole-system waterproofing design. Waterproofing is not a single-material issue but a systems engineering task, requiring comprehensive control over materials, construction details, and workmanship.

Hydrophobic Panel Surfaces Are the First Barrier

Silane impregnation achieves a contact angle ≥110°, reducing water absorption to below 1%. Qinglong Group uses high-pressure spraying to ensure uniformity. In the Zhuhai project, the hydrophobic treatment delivered remarkable results. Regular maintenance preserves the effect.

Joint Sealing Is the Key Link

The sealant offers weather resistance ≥25 years, with application thickness ≥ 1/2 of the joint width. We train professional sealant application teams to guarantee quality. Inspection and acceptance leave no hidden risks.

Qinglong Systems Are Time-Tested
