Photo Album: A driveway that had uneven slabs is repaired using the PolyLevel Injection System in Hebron, Kentucky.

This driveway had some uneven slabs.  Over time the ground under the concrete slab can compress or wash away.  This causes a space under the slab causing it to sink.  The PolyLevel Injection System injects an expandable foam under the concrete through a small hole.  As the foam expands, it raises the slab.  After a short curing time, the driveway will be ready to use again.
