Auger Underpinning
The underpinning of foundations by drilling a series of auger holes under the foundations. By part filling with concrete it is possible to lift the foundation with hydraulic jacks, before totally filling with concrete.

underpinning a foundation

This method of underpinning sagging foundations has the potential to be able to lift the foundation back to it is original position.

A series of holes are drilled under the sagging sections and and hand worked to remove the soil where the auger could not reach. Then every second hole is part filled with concrete. Depending on the depth the holes may be 300 dia. or 600 for more working space.

When the concrete has cured a hydraulic jack is used to lift the footing and it is packed with steel packers.

Then all of the holes are filled up higher than the bottom of the footing.
