Subway waterproofing has always been a key focus in subway construction. Due to the damage of water seepage to concrete structures, the service life of subway projects in China often fails to meet design expectations. At the same time, during the operation period of the subway, the water seepage problem seriously affects the traffic safety of the subway, and the leakage problem of the subway station also often becomes a hot topic in a city.

The traditional mining method tunnels are basically made of plastic sheets (EVA, PVC, ECB, etc.) as the main materials for waterproofing and defense. Under the existing construction conditions and organizational forms in China, leakage is common, seriously affecting driving safety and structural life, and bringing a heavy burden to later maintenance.

Building waterproofing engineering is a project that ensures that the structure of a building is not affected by water and the internal space is not harmed by water. Although the cost of waterproofing engineering only accounts for about 1% of the project construction cost, it plays an important role in the entire project. Complaints caused by leakage account for 65% of the total building complaint proportion.
