2009 IRC, section 317.1 #5.
Has anyone required details on how this will be accomplished where they want to have their concrete porches/patios at the same elevation as their finished floors?
The way this reads, it does not appear to be enough to simply protect the wall or sheathing with a moisture impermeable barrier, or even to cover the wall framing with P.T. sheathing. The wall framing itself needs to be P.T.
We have been throwing this around for some time now. The only way we can see this happening is to have (2) P.T. bottom plates, P.T. sheathing, and something other than wood siding (unless naturally durable wood, etc) within the first 2 inches.
It seems odd that they can apparently pour the concrete against an impervious moisture barrier protecting a floor assembly such as at a rim (#7), but they still need 2" to the wall framing, sheathing, siding, 2" above the concrete slab.
Any thoughts?
