PROBLEM TO BE SOLVED: To provide an impervious structure of a storage facility wherein repair of a broken part of an impervious sheet is completed in a short period of construction work and which is suitable even to emergency treatment.SOLUTION: This impervious structure 1 of a storage facility includes: a lower impervious sheet 4 laid in a bottom part 15 of the storage facility; the upper impervious sheet 5 laid above it; and a plurality of horizontally partitioned intermediate protective soil layers 11 provided between both the sheets 4, 5. Each of a plurality of injection pipes 3 each having discharge parts 12 is disposed inside each intermediate protective soil layer 11, and the discharge parts are disposed in each partition. Because an application electrode 7 and measurement electrodes 8 are provided on the upper impervious sheet 5 side correspondingly to each partition, the broken part 13 of the upper impervious sheet can be specified by the positions of the measurement electrodes, wherein current carrying is detected. When injecting a slow setting injection material 14 from the injection pipe 3 disposed in the partition, the slow setting injection material arrives at the broken part while the inside of the partition is filled with the slow setting injection material, and the broken part is repaired.
