Apartment Floor Lifting

Apartment Slab Foundation Repair, Portsmouth, VA



Floor slab foundation settled up to 3 inches in the center of two adjacent (but separate slab) apartment units in Portsmouth, VA. One unit was the property’s office, the second was being turned around between tenants, so repairs had to be effective, fast, economical and non-disruptive.


High density polyurethane foam jacking for this foundation repair project. Foam jacking can lift both structural (load-bearing) and non-structural areas of floors, so this home was a relatively light duty application. Previous repairs by Concrete Jack at the same complex had been completed using mud jacking, but those units were gutted. These units were in good shape on the interiors, and speed was critical, so foam jacking was chosen as the most appropriate repair, and was actually less expensive than the previous mud jacking repairs in similar units.


Concrete Jack foam jacking crew installed NCFI high density polyurethane to raise the settled portion of the slab foundations back into place. The work was completed in a total of six hours for both units. The customers were able to install the new floor they wanted immediately afterwards, and repair the cosmetic cracks to the interior walls starting immediately after the foam jacking was completed. The office remained in use during the repair.
