    Default What is this called?

    Anyone know what this type of foundation stabilization structure is called? How about info on installation, etc.? Saw them today on a multi-unit condo structure that was originially built on wooden piers near Lake Superior and, apparently when the wood started to sink and rot, the building was supported by these structures.

    Richard is right, it is used to jack up and support a foundation that has settled.

    I have heard them called helical piles or helical piers. I have seen these a couple of times. While they are apparently effective, I wonder about their longevity. The metal will probably rust out eventually. It seems to me that encasing them in concrete would be a good idea, but maybe too expensive.
