Good evening everyone, my question is this. We are beginning the planning phase of construction.. of course our first optical to overcome is a solid foundation, only where we would like to build is on solid rock. What would be the best method to go about this.. We are think about using ICF block construction for the home or at least the first two feet then perhaps log on top of that.. We do get high winds in this area so obviously we need a strong solid foundation.. Any ideas on what the best method for laying a foundation on solid rock would be?? Help..
You need an engineer, and he may want/need a site characterization. Ledge, thickness, type, stability, likeness to shift side to side, up and down, etc. Rock can make a very stable foundation; however, it can also be more apt to shift than normal soil under certain conditions.
I have a friend whom built on Lake Champlain up here. His lot was basically a ledge. He dug to the ledge. They drilled and shot anchors of some sort into the ledge and his footings were poored directly on it. It was a very overbuilt place (that's his style) but nothing ever moved. He had mammoth footings, one in the center of the house that was like 8'x8'x4' that supported a granite planter box which separated the dining room and kitchen. There was another for a similary constructed fireplace.
