The previous owners of our home did a foundation repair to fix two large cracks about 10 years ago (it is covered by a lifetime warranty). The repair was very successful, but the epoxy plugs remain.
In an effort to improve the efficiency of the home, I want to apply rigid foam (xps - 2" on walls, 1" on floors). I am left scratching my head however on how to do this on the wall with the epoxy plugs. I've included a picture below of the plugs for reference.
The best option I can think of is to strap the was with 2x2's or 2x3's first. Thoughts?
