We have a couple of wood docks on Earl lake where I live, that are pretty big, built on wood stanchions but they are in about 12' to 15' of muck and marrow bottom. They don't seem to lift that I know of, but that is a lot different type of bottom. My apprehension is that the clay will be impenetrable at a much shallower depth and would not therefor offer as much resistance to lift. The contractor I have lined up for the job seems more interested in achieving downward support than the ice lifting potential.
I'm Wondering if maybe I should wrap some sheet metal around each post at the waterline so the ice dosen't have anything to grab onto?
