The technology to lift concrete is centuries old. It is the same technology that is used to raise your car on a hydraulic lift at the car repair garage . Holes are drilled through the tilted concrete, usually one to two inches in diameter. A mixture of mortar and water is then pumped into these holes under pressure. This mixture has the consistency of a thick mortar. As it begins to flow beneath the slab, it exerts an equal pressure on every square inch of the concrete. Thus, if the pump produces just 50 to 100 pounds per square inch pressure (which isn't much) it can easily raise the slab.
