First off, one of the chief benefits that comes with concrete lifting that you just don’t get with replacement is speed. Specifically, the speed of the process and the speed of recovery. When you put in a whole new concrete slab, you must first demolish and remove the old one. What is worse is that once that process is completed, you are still only halfway done! A whole new slab must be poured, smoothed, and left to dry, which can take days to complete. None of these are issues with concrete lifting. Through a relatively simple injection process, you can be standing on level, good-looking concrete in as little as two hours!
