I watched your videos with much interest but wasn't sure about the "trench" type perimeter "grade beam" in terms of supporting the house structure, and the fact that I have bedrock (Lake Huron / limestone) 18" below the surface. Wouldn't a poured perimeter wall down to bedrock be a better approach - before pouring the slab?
