The approach to my garage has sunk on the edge that approaches the garage by 3 to 4 inches. I have been told mudjacking is economical and because of this is my preferred method of repair. The slabs of concrete that run along the approach (both have sunk) are about 6 feet wide. The concern I have is that each slab is only about 2 feet from front of slab to garage entrance. Would this slab be too narrow to mudjack? It only needs to be lifted on the edge that runs along the garage entrance. Possible? Not enough info?
