I am looking for advice before I frame this wall. It is the front foundation wall. You can see the rim joist never had any insulation. I am considering using a big gap foam spray. I used a temperature scanner and all along the top I am getting 58-62 F. Notice the small crack. The house is 35 yrs old. Should I have a foundation repair person inspect?

Hi Michael, since you are finishing your basement and covering all of the structure up, you must ensure that it is sound and water tight. It can never hurt to have a professional look at your particular situation.

Post your requirements in the projects area and I am sure that you will get some responses from the right people.

Good Luck,

Hi Michael

I agree with Jim, have it looked at, the crack appears to extend to a spacer bar hole, used to hold the forms apart and will most likely leak, epoxy injection usually works well above grade. As far as insulation goes I would use fiberglass if you can get at it, and don't forget the typar. 1/2lb foam is not a good option unless you have to, and 2 lb. is expensive, and should be used with 2.5" foam board (r12 new code) on the rest of the wall. Another important part is to caulk the gap, if any between the sill plate and the foundation to stop air flow, you need to deal with the sill wrap first. Fold up the sill wrap and hold it with staples, the dark green plastic in the photo, cut it a couple of inchs up from the foundation wall, this is important, it can act as a vapor barrier on the rim board if wraped all the way up.
