Background
Located in Xingtai City, Hebei Province, the Xingtai Museum is a comprehensive cultural institution integrating collection, exhibition, research, public education, and cultural exchange. It is also the museum with the largest exhibition area in Hebei Province and was named one of the “Top Ten New Landmarks of Xingtai” in January 2020. As a landmark cultural building, the Xingtai Museum demanded exceptionally high standards of durability and impermeability during design and construction. The underground structure and roofing system faced long-term challenges from groundwater infiltration and temperature fluctuations, requiring a long-lasting, environmentally friendly waterproofing solution that would not compromise the building’s aesthetics.
Solution
The foundation of this project utilized the KIN FLAGO DR HDPE pre-applied waterproofing membrane. The roof employed the JOYA FN EZFLEX non-curing waterproofing coating combined with the KINJOYA FM PLAIN SBS waterproofing membrane, while the interior areas used the KINJOYA PU series polyurethane waterproofing coating. For complex roof details such as equipment bases and skylights, a composite system was applied, featuring a continuous sealing layer formed by fully bonding the non-curing coating and the SBS membrane. Interior floors received three coats of PU coating, achieving a dry film thickness of no less than 2mm. The KIN FLAGO DR HDPE membrane offers high tensile and puncture resistance, suitable for long-term humid underground conditions. The JOYA FN EZFLEX non-curing coating maintains flexibility between -20°C and 80°C, effectively adapting to temperature variations. The FM PLAIN SBS membrane and the non-curing coating work synergistically, forming a “rigid-flexible” roof system with enhanced crack-bridging and self-healing capabilities.
Outcomes
The project successfully achieved long-term waterproofing objectives for the roof and underground structures, significantly reducing future maintenance costs. Specific techniques and material applications effectively enhanced the strength of the concrete structures, improving their resistance to freeze-thaw cycles and overall durability, thereby extending the building’s service life. The materials used are non-toxic and environmentally friendly, making them ideal for public buildings like museums where safety and environmental standards are paramount.
