Question:

Is treated lumber permitted to replace the concrete curb block on the interior wall footing?

Answer:

Yes, if the lumber was treated for ground contact, properly anchored, of proper width, and at least the thickness of the slab.

Comments:

The concrete floor slab could be poured against the sides of this "plate," and a treated 2x could then be installed on top. A (.60 C.C.A.) foundation grade material is not required because this is not part of a treated wood foundation system
