These problems can be repaired by our concrete lifting foam process.
We drill small, dime sized, holes through the concrete and inject specially formulated polyurethane foam under the slab. This liquid foam fills all the voids under the slab and as it expands it lifts the slab and further compacts the ground below it to minimize the probability of future settling.
Jacking concrete with polyurethane is better than the traditional mudjacking process for two primary reasons. First, the foam used weighs about 2 pounds per cubic foot, whereas the slurry used in mud jacking weighs about 100 pounds per cubic foot. Using foam significantly lessens the weight that could cause future settling. Second, after the foam is installed it becomes an inert plastic and it can't be washed away by water which is a primary cause of concrete settling.
This concrete sidewalk repair needed to be lifted a full brick on the left side and 1-1/2 bricks on the right side. Using polyurethane foam we were able to change this from a 12 inch drop off to an 8 inch step and level it from side-to-side.
