20140290169 | UNEVEN CONCRETE SLAB REPAIR SYSTEM AND METHOD - This invention is directed to a main beam having a distal end that contacts a high side of a slab to define a pivot point; an anchor removably attached to a low side of the slab; a coupling attached between the anchor and the main beam so that when a proximal end of the beam is raised, the low side of the slab is raised; a jack coupled to the distal end for raising the proximal end of the main beam; a void defined between the surface under the slab and a bottom side of the slab when the slab is raised; and, filler material inserted in the void so that when the filler supports the slab after the anchor and beam are removed resulting in an evened slab. | 10-02-2014 |
