An area of the Homeowner's front walk way was settling, which is very common in this area. With the technology of PolyLevel, we were able to bring the sidewalk back up to a level position.
The stem wall of the Tucson, AZ home was showing signs of failure. Stem walls crack, spall, and flake when the rebar inside becomes oxidized which weakens the concrete. Our stem wall repair crew cut out the existing rebar and replaced it with our non-ferrous composite.
Composite interlocking can be performed to tie the broken pieces of the concrete together. The existing cracks will be cleaned and non-parallel lines will be cut across the existing cracks. Next carbon fiber laminate stitches will be inserted into the non-parallel cuts and then the gaps will be filled with a 2 part poly.
Finally, the crack should be ground smooth to minimize the differential. If done properly, this will allow the slab to function as one floating unit to help prevent the damages to flooring, ceiling and walls. If this is instead expansion joint separation, the joint should be cleaned, routed, and re-caulked with an expansive joint filler.
After examining the home and performing the manometer survey, we believed the home could be experiencing foundation settlement at the north side, the south side and the west side of the home.
Our solution to the foundation settlement issue this home was experiencing was to underpin* the areas that are experiencing movement. *Underpinning is the process of installing deep foundation elements called piles. These piles are driven down past the unstable soils and are then locked up into load bearing strata that can support the loads that are put on them.
This home's new owner wated to address the foundation issues currently presenting in the house.
