Slab on grade foundations

GBA Editor | Posted in Green Building Techniques on

I am building a slab on grade 24ft. X 24ft. cottage in upstate pa. I will be using a 12″X6″ footer with 5 course of 8″ block around the parimeter foundation. 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?
