Slab settlement in Pierrefonds, Québec

We repaired the basement slab that was sagging at this house in Pierrefonds. Symptoms can be clearly seen in the cracks separating between the top of the interior walls of the basement and floor upstairs. By installing our slab piers, we did not just stabilize the slab, but also we were able to close the existing cracks as you see in these 2 pictures.
