Zusammenfassung:	PURPOSE:To stop the leakage of water in concrete structure in contact with the earth. CONSTITUTION:An injection hole 3 passing through an underground concrete structure 1 is formed in the lower part near cracks of rockpocket of the underground structure 1. A grout 5 composed mainly of slag-based fine particle cement is injected into the hole 3, where the grout 5 permeates into the crack of the rockpocket by pressurized permeation flow and capillary permeation flow of the groundwater in such a way as to completely join the grout 5 with the concrete by hydrating reaction.
