Foundations, Footers, and Slabs

Conventional foundations, footers, and slabs use a lot of concrete, which is energy-intensive and polluting to produce—up to a ton of CO2 is released in producing a ton of cement. Admixture components such as calcium chloride (an accelerator), gypsum (a retarder), and sulfonated melamine formaldehyde (SMF, a plasticizer) also affect the environmental impact of the concrete. Depending on the chemical, the impact may be on-site or at the plant. Also, concrete foundations and slabs do not provide much by way of thermal insulation, though they can provide thermal storage.

What did you find out?
by jklingel

I just came across this post, and am curious about what you ended up doing. I wondered why the same footer you used on the exterior walls (maybe a tad larger) would not suffice for the interior load bearing wall. Thanks. john

On top of that i will have a 4" slab. the frost depth is 36" I will have a interior load bearing wall running through the center of the structure.What is the approved method of support, under that interior load bearing wall and pad.
