PolyLevel Injection System used to raise a concrete sidewalk slab, in Wilmington, Ohio.

We used the PolyLevel Injection System to raise a concrete slab in Wilmington, Ohio.  Over time, the ground under a concrete slab can compress or wash away causing the slab to sink.  This can also create a tripping hazard.  The PolyLevel Injection System can be used quickly, with little mess, and will be ready to be used again very soon.
