Foundation Replacement
Perhaps the ground beneath your house is fine, and you simply need its shallow, old foundation replaced.
We can put a basement under an existing house. In this example, we installed four 3.5" diameter round shaft helix piers to support the interior of a two-story one hundred year-old Victorian, then excavated around the helix piers. These heavy duty helix piers have ample lateral strength to stand without lateral soil support.
