Ideas for air barrier for stepped foundation wall
My house has a couple of unusual conditions:
1. Extra deep footings in south wall because of poor soil conditions. 8' below grade.
2. Using an ICF foundation, but ICF is not made out of foam board, but is composed of blocks like CMU made out of a wood chip/cement mix that is air permeable (Durisol).
I'm worried that air can go from interior through inner wall of the ICF down and around the slab into the soil underneath the slab.
a) Is this an issue?
b) How to address? I was planning on parging interior basement walls sometime in the future with clay. For now, would parging the wall with cement below the slab to the footing work?
