Concrete Grinding. At A-1 Concrete Leveling, we understand that sometimes a slab just can't be lifted. This may be due to the location of the slab, or the fact that the concrete slab is tied in physically with another part of the structure. In cases like this, concrete grinding might be the only available option.
