Claims17
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;
