YURU Waterproof Materials Successfully Applied in Nanjing Metro Waterproofing Project
Project Background
The Nanjing Metro is one of China’s most important urban infrastructure projects, designed to provide safe, efficient, and reliable public transportation for millions of passengers every day. Due to the underground structure, the metro tunnels and stations face significant challenges from groundwater seepage, structural cracks, and long-term exposure to moisture.
To ensure long-lasting durability and passenger safety, the project required advanced waterproofing materials with excellent crack-bridging ability, chemical resistance, and adaptability to complex construction environments.
