In 2 weeks I will be starting the actual build of my ICF house in SE Tenn. All excavation is done of the drive out basement except for the footers. Soil is red clay, no rocks but the clay sure is hard. House will be 2 floors of ICF 6" block with rebar both ways.
I'm planning on a 12"DX24"W footer.
My question [s] are,
What should my footer depth be?
Would pouring the slab and footers at the same time be benificial? I like the idea of working on concrete better than rocks or red clay. Will make the supports easier to attach to.
I've read about wet setting the first course, filling and pouring the slab to it before continueing up but that seems to be more for the pros.
