WATER LEAKAGE REPAIR DEVICE AND METHOD FOR WATER LEAKAGE REPAIR

摘要

PROBLEM TO BE SOLVED: To provide a water leakage repair device and a method for water leakage repair that block water leakage from concrete structures for certain, by improving the quality of water-shielding layer formed on an undersurface of an existing concrete structure.SOLUTION: A water leakage repair device 1 has a support base 2 inserted inside from outside of a gap 6 formed underneath a concrete structure 5. The support base 2 has either or both of a spray device 3 that sprays a water-sealing material 70 at least on an undersurface 5a of the concrete structure 5 and a confirmation device for confirming the sprayed condition of the water-sealing material 70 that has been sprayed at least on the undersurface 5a of the concrete structure 5.
