A floor slab support system for jacking and stabilizing a sagging or cracked floor or other such slab. Holes of 3½'' diameter, for example, are drilled through the slab and a pipe pier driven downwardly until reaching bottom. A connector sleeve matching the slab hole size is temporarily suspended in the slab hole and L shaped brackets are inserted into the sleeve and maneuvered to extend outwardly through slots in the sleeve to engage the underside of the slab. A threaded rod with a threaded positioning member and a bottom stop is inserted through the sleeve and into the pipe pier, and the L brackets extended through the sleeve and maintained outwardly by the threaded positioning member. Once in position, the threaded rod is rotated to screw the sleeve and brackets upwardly to support the slab. Finally, the top of the rod is cut off and the hole filled with concrete.
