Safety, Durability, and Usability of the Concrete Structure affecting among, there are crack and leakage the main damage is crack and leakage. Especially, Leakage is accompanied by Efflorescence, and provoke steel corrosion, exfoliation. This leakage is leaked to the exterior of the concrete surface in the shape of line or face, the method of repair varies with the shape of leakage. Accordingly, this paper will introduce case analysis of the shape of the water leakage to water leakage site in the lining structure of the NATM tunnel for utilize investigation method and basic data for the method of repair.(leakage, Efflorescence)
