Abstract: To address the problem that existing negative-side inorganic waterproofing & leakage-preventing materials tend to crack under external forces due to excessive rigidity, consequently losing their waterproofing effectiveness, this study developed a novel rigid-flexible composite material by incorporating three types of high-performance polymer fiber fabrics (7 variants in total), i.e., polyester T, polypropylene PP, and alkali-resis-tant polymer fiber fabric GT, into conventional inorganic waterproofing materials. The tensile properties, tear resistance, bonding performance, peel resistance, and waterproofing/impermeability characteristics of composite materials at negative-side surfaces were systematically investigated. The internal mechanisms were elucidated through analyses of penetration height, fiber thickness, and microstructure observations. Results demonstrated that polymer fiber fabrics effectively enhanced the deformation resistance of inorganic waterproofing materials while maintaining excellent interfacial bonding. The composite materials also showed outstanding performance in waterproofing and leak preventing applications. The composite exhibited superior performance, which correlates with: ⅰ) interfacial bonding between hydration products and polymer fibers; ⅱ) sy-nergistic effects between fiber thickness and waterproof coating thickness; and ⅲ) interfacial interactions between fibers and coatings. In particular, the alkali-resistant polymer fiber GT showed exceptional suitability for negative-side leakage repair applications due to its optimized compatibility and performance characteristics.
