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


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


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
