Settled Concrete on Front Porch Walkway

This customer was worried that her home was a tripping hazard due to concrete settlement. The biggest area of concern was the front porch. When we inspected, we found that the two slabs on their front walkway had settled at a couple different joints. This happened due to the soil underneath the slab drying out and shrinking, then eroding away when it would rain. 

To fix, we injected a poly foam to lift the slab and eliminate the tripping hazard. We then sealed the joints with a joint sealer to make sure moisture doesn't find its way under the slab again.
