Inverted thickened edge slab. Work?
Having looked at a variety of foundation systems, I see problems with all of them. Any stem wall or thickened edge generates insulating or compacting/pouring issues, as far as I can see, especially w/ lots of foam underneath. This one is not perfect, either. Nevertheless, here is an option I thought of that gives you the rigidity of the thickened-edge slab but is easier to insulate... except at the garage door. It also better locks the house to Terra Firma than a SOG, should there be seismic activity, .... I think it does, anyway. This generates a 4" lip to drive or step over. Firring out the floors w/ 2x4s or ramps would be work-arounds, or dropping the edge below the garage door and back up on the other side; not fun. Any feedback on the viability of doing this is welcomed. It is just a thought, after all. Thanks. john
