Commercial buildings can prove to be just as vulnerable if not more vulnerable to concrete settling than residential concrete slabs. In many cases, commercial slabs are under much more constant weight of machinery and equipment. Just recently, we were hired to raise the failed concrete flooring of a commercial building. Throughout this blog, we will walk through the stages, thoughts, and execution of the job.
When raising concrete slabs that are very large and have differing heights, it is important to have numerous polyurethane guns injecting foam under the slab at once to disperse the weight. We sent three crews to this site for this reason
Before the crews began injecting the foam underneath the slabs, they had to come up with a game plan for port placement and where to begin the lift. Taking your time placing ports in strategic spots is a necessary starting point for a successful lift. The images attached below show how far the concrete had settled overtime to the interior wall of the building. This settling could have been the result of the heavy equipment on the slab working with the poor soil compaction.
Once the work was finished, the failed and sunken concrete was back to its originally poured location with contact against the walls. By choosing to use Liftech’s concrete leveling services rather than ripping out and repouring the slab, the customer was able to save a large amount of money and time. The whole process only took a few hours whereas a new floor would have taken weeks and caused a massive slowdown in production.
If your commercial building is facing concrete failure, call Liftech for a free estimate and get your business back to production as soon as possible.
