Our craftsman style house was built in 1923 and currently has an 8' x 30' concrete slab porch, 6" thick. The porch rests on a block foundation. I'd like to have a wooden porch. Since it will be too expensive to remove the existing concrete porch, I am looking for a way to apply wood decking on top of the concrete. We only have about 1.5" from the top of the slab to the door's threshold. Would like use real wood (T&G)not a composite material. Any ideas on how to construct this so that the wood will not rot from the bottom? Thanks for any ideas!
