I've leveled the previously bottom stair cement slab (20" x 48" x 20" deep).
I now need to pour a new 7 3/4" high "bottom" stair in front of the leveled slab, above.
I intend to use rebar in the new bottom stair (2 - 4' rods and 2- 1' rods in a rectangle supported by two wire cradles to position the rebar in about 5" about the bottom of the slab).
I like to ask the group how much deeper/thicker should the slab be to sit firmly in the ground? Asphalt will be laid right up to the front of the new bottom stair, which should hold it in place, some.
TIA for any tips, suggestions, comments.
