<P>PROBLEM TO BE SOLVED: To provide sunk floor correction method capable of accurately correcting a sunk floor inexpensively in a short construction period. Ž<P>SOLUTION: In the floor constructed on a ground, injection holes are drilled for injecting an expandable resin at and around the center part in the sunk area. Next, the expandable resin is injected to the underside of the floor through the injection hole drilled at the center part to raise the floor around the center part a predetermined amount by the expansion force of the expandable resin. Then the expandable resin is injected to the underside of the floor through the injection holes drilled around the center part to raise the floor around the center part a predetermined amount by the expansion force of the expandable resin.
