Its eastern and southern sides are adjacentto subway lines. To mitigate leakage risks in the basement exterior walls, cement,based permeablecrystalline waterproof self,healing concrete was adopted. This paper outlines the self,healingcharacteristics and application procedures of capillarywaterproofing materials, and evaluates theeffectiveness of the self,healing concrete through on,site monitoring and analysis of crack repair in theexterior walls.
