Frequently, foundation problems in the Big Country are the result of the perimeter of the foundation settling. When the steel piers are installed under the perimeter grade beam and the foundation is returned to its original position (raised), a void is created under the slab. In some instances, it may be necessary to fill this void to properly support the foundation. Mudjacking to fill this type of void is accomplished from the outside of your home by drilling 2' holes throughout the perimeter grade beam and pumping a mixture of soil/cement grout into the void.
