The alternative of jack hammering out a section of concrete is not all that simple. To be done correctly, the section being removed must be saw-cut and then drilled and pinned with at least #5 rebar. This way, the new concrete is tied into the existing floor for better strength.
Also, gotta allow for sufficient cure time on the new concrete. The good news is with this method you don't have to drill holes for the base plate of the lift. Just manufacture a template and "set" the bolts into the uncured wet concrete.
Quote:Bill is absolutely right about the importance of the concrete, particularly the depth. Drill a hole before buying to check. The alternative is jack hammering and laying down a new patch that's up to the task.
