Virginia Beach, VA (PRWEB) March 31, 2013

The floor inside of a commercial building, housing a t-shirt shop and restaurant on the oceanfront in Virginia Beach, Virginia settled up to 11 inches. The geotechnical engineer determined that the underlying soils were unsuitable, and recommended high density polyurethane foam jacking for the repair. Because high density polyurethane is very lightweight (4 pounds per cubic foot), it lowers the chances of resettlement when compared to cement-based grouts (120 pounds per cubic foot).

Concrete Jack was chosen as the polyurethane foam jacking contractor to complete the project. Two polyurethane foam jacking crews lifted the floor back to its original position, for a fraction of the cost and time required to replace the floor.

Chemical grouting was also performed to stabilize the areas of soil immediately under structural columns for the roof.
