Concrete slab against rim joist
So I am in the process of repairing the damage caused by someone pouring concrete up against my rim joist once upon a time. Broke out the concrete and replacing the damaged mudsill and rim joist with ground rated pressure treated lumber. The thing is, I really need to pour concrete back up against it. It will be covered, but the house was built to low for the existing grade. I have spent some time researching this and it sounds like while not optimal, a pressure treated sill and rim joist with a peel and stick membrane with an additional metal flashing might be a reasonably effective combination. Does anybody have a detail for this process?
Also, in another area with a similar problem, I am considering adding a row of block on top of the existing foundation wall and joist hanging off the inside. This portion of the house is currently under grade. Dirt was halfway up the mudsill. This portion will not be covered with a porch and will have to have finished grade 6″ down from subfloor level. I would love to do peel and stick and flashing like the drawing I attached. Any thoughts on these ideas?
I am in Southern Oregon.
