Background
The SNPTC Zhongguancun Campus, located in Haidian District, Beijing, is a modern industrial park integrating scientific research, design, and office functions. The waterproofing project was implemented to meet Class A Level 1 waterproofing standards, covering critical areas such as roofs, basements, equipment rooms, and laboratories to ensure a safe and stable research environment.
Solution
The foundation used KIN FLAGO DR HDPE pre-applied waterproofing membrane. The roof used a composite system of JOYA FN EZFLEX non-curing coating and KINJOYA FM PLAIN SBS membrane. Interiors used KINJOYA PU series coating. For complex roof details, the composite system provided a continuous sealed layer. Laboratory floors received three coats of PU coating, achieving a dry film thickness of at least 2mm. The KIN FLAGO DR HDPE membrane offers high puncture resistance for long-term humid underground conditions. The JOYA FN EZFLEX coating maintains flexibility from -20°C to 80°C, adapting to Beijing’s temperature variations. The FM PLAIN SBS membrane and the non-curing coating work synergistically, forming a rigid-flexible roof system with enhanced crack resistance and self-healing capabilities.
Outcomes
Since the campus opened, it has achieved zero structural leakage in the research area, protecting high-value equipment and data security. The waterproofing system supports the campus in meeting Green Building 2-Star or LEED certification standards, reducing long-term operational energy consumption. It has established a waterproofing system paradigm for high-end research and office buildings, offering industry-wide demonstration value.
