Claim:
A method for constructing a pier system to stabilize and level a structure, the method comprising: constructing a pier comprising the steps of: forming hole about 26 inches below the foundation; placing a pier base having a base cylinder portion in the bottom of the hole; placing a first outer cylinder over the base cylinder portion; inserting a first inner cylinder inside a recess in the first outer cylinder, the first inner cylinder butting against the base cylinder portion; and repeating the steps of adding an additional overlapping outer cylinder and an additional inner cylinder providing a 50 percent overlap of consecutive cylinders creating a link between the outer cylinders and advancing the cylinders downward using a hydraulic ram until bedrock is reached; completing the piering system comprising the steps of: cutting the top most cylinders to be approximately ten inches below the foundation; positioning a head plate on top of the pier to provide a stable platform for a house jack; positioning the house jack on the head plate; positioning a heave plate between the house jack and the foundation; using the house jack to apply a vertical lifting force to lift the foundation of the structure to adjust the structure, the heave plate distributing the lifting force to avoid damage to the foundation; after adjustment is finished, positioning additional jacks on the head plate on either side of the house jack to support the foundation; removing the house jack; positioning a shim block and coupling assembly on the head plate; advancing the coupling assembly upward until the coupling assembly reaches into a socket of the heave plate; removing the additional jacks; drilling holes through the holes in the heave plate into the foundation; and driving concrete anchors through the holes in the heave plate and into the holes drilled into the foundation to fix the heave plate to the foundation.
