Stoop Repair (Lifting), Alexandria, Virginia
Stoop at entrance to townhouse settled, causing an awkward step up into the house.
Foam jacking crew injected high density polyurethane under the concrete to raise it back up and complete the stoop repair. The work took about 30 minutes, and the homeowner was able to walk on the slab right afterwards.
Foam jacking lifts settled concrete by injecting lightweight, high density polyurethane under the concrete through dime-size holes, where it expands to fill voids and push the concrete back up. Foam jacking is excellent for sidewalk repair because the holes are small, the repairs are fast and do not disturb the surrounding landscape.
