Advances in Constructional Engineering

As a new type of building material, self-healing waterproof materials are designed to address the common leakage problems in underground buildings, and to improve the service life and safety of buildings. This paper studies the design principles of self-healing waterproof materials and their application effects in underground buildings, and explores how their self-healing mechanism can effectively prevent water intrusion and extend the structural lifespan. Through laboratory tests and analysis of actual engineering cases, it has been verified that this material can not only effectively waterproof, but also automatically repair after being damaged, reducing maintenance costs. The adoption of this advanced material can significantly enhance the waterproof performance and durability of underground construction projects, providing new ideas for the development of building waterproof technology in the future.
