Getting a better understanding of how house lifting is done

In a nutshell, house lifting is the process of strengthening the building. Elevate the building. Brace. Raise it yet again. Repeat.

The fundamental procedure is a little more involved and time-consuming, but that's all there is.

Most house-lifters follow a regular procedure that involves running steel beams beneath the house, then elevating it with synchronized jacks while adding cribbing underneath.

This process is completed in steps. The critical components required are hydraulic jacks for house lifting and cribbing for support.

The house-lifters separate the house from its foundations during the elevation procedure and raise it on hydraulic jacks. Cribs, or temporary supports, keep them in place while a new or more significant foundation is erected below.

To begin, holes are drilled at regular intervals in the foundation wall so that a series of steel beams may be placed at critical locations beneath the floor framework.

Each beam is placed perpendicular to the ground. The second set of beams is installed below and perpendicular to the first.

Once each steel beam and jack are in place, the elevating procedure may begin. The jacks are evenly distributed beneath the house and are attached to a single piece of hydraulic jacking equipment that can precisely raise each jack at the same time. The house and hydraulic jacks are supported at regular intervals while the jacks are raised because each jack can only go so far.

After the house has been elevated to the proper height, it is cribbing again while the new foundation walls are built to the required dimensions. The house is then dropped into the reconstructed foundation walls, the beams are removed, and the steel beam holes are filled.

This method works best with houses with a partial basement, crawlspace, or open foundations.
