Pressed Piling Pier Benefits


How concrete piers are installed

A two foot square hole is dug by hand with a shovel. The hole will typically be four or five feet below ground level and will extend under the grade beam of the home to be lifted.

A pre-formed concrete cylinder (6′ diameter by 12′ tall with a ¾’ hole down the long axis) will be placed at the bottom of the hole directly beneath the grade beam. A 40 ton hydraulic ram will then be placed between the bottom of the grade beam and the top of the concrete cylinder.The ram will then be engaged and the cylinder will be pressed into the ground.

Each cylinder will be connected with epoxy and steel rebar. Cylinders will be added and pressed until the point of refusal. That is to a point where it takes more force to press the piling deeper than it does to lift the house. This process is repeated until all the pilings are installed. Each piling will then be fitted with a concrete cap. The house will then be lifted using 20 ton bottle jacks. The house will be lifted to as near its original position as possible without causing unacceptable damage to the foundation or structure being lifted. Two cylinders set atop the cap with steel shims used to fill the gap between the bottom of the grade beam and the top of the piling. The holes will then be backfilled with the existing dirt.
