(57) The problem of the present invention is to provide a method for correcting the inclination of a concrete slab, when one side of the concrete slab sinks due to subsidence of the ground, by returning the one side of the sunken side to a predetermined height. A solution therefor comprises at least: a step (1) for providing a side groove in which a jack for lifting the concrete slab from a side is installed along the sunk side of the concrete slab; a step (2) for installing the jack in the side groove and lifting the concrete slab from the side; a step (3) for injecting and expanding an expansive resin from an injection hole formed by drilling the concrete slab in a gap below the concrete slab formed by lifting the concrete slab with the jack; and a step (4) for removing the jack installed in the side groove.
