Claim:
An apparatus for lifting and stabilizing a slab comprising: a) a bracket, wherein the bracket comprises: i) a means for receiving an end of a section of pier column, wherein the means for receiving an end of a section of pier column can be positioned over a base pier column under a subsided slab with a top section of pier column supported by the base pier column and positioned within the means for receiving an end of a section of pier column with a top of the top section of pier column extending above the means for receiving an end of a section of pier column, ii) a means for supporting a slab, wherein the means for supporting a slab is fixedly attached to the means for receiving an end of a section of pier column, and iii) one or more bracing means, wherein the one or more bracing means is positioned relative to the means for receiving an end of a section of pier column and the means for supporting a slab such that the one or more bracing means provides additional support for the means for supporting a slab; and b) a means for lifting the bracket, wherein the means for lifting the bracket lifts the bracket with respect to the top of the top section of pier column such that the slab is lifted to a desired level, wherein the means for lifting the bracket comprises: a top piece, wherein the top piece is positioned over the top of the top section of pier column such that the top piece rests on the top of the top section of pier column, wherein the top section of pier column provides support for the means for lifting the bracket; and means for raising the bracket with respect to the top piece, wherein the means for raising the bracket with respect to the top piece comprises at least one rod, wherein each of the at least one rod connects the bracket to the top piece, wherein a portion of the at least one rod extends above the top piece with the top piece positioned over the top of the top section of pier column, wherein the means for raising the bracket with respect to the top piece further comprises: a plate, wherein the plate is connected to the portion of each of the at least one rod extending above the top piece; a means for raising the plate with respect to the top piece, wherein raising the plate with respect to the top piece raises the bracket with respect to the top piece.
