I have an ICF foundation with a 1x at ground and below grade that is pulling away from the foam form

Al in NB | Posted in General Questions on

I have an ICF foundation with a 1x at ground and below grade that is pulling away from the Foam form. How do I correct?

Debris has gotten between the wood application and the foam form. Is this a problem to the integrity or simply a cosmetic problem? What is the best way to repair or replace?

    Al,
    It would be helpful if you described the purpose of this 1x. If you need to fasten something to an ICF wall, the most secure way to do that would be with a concrete screw like a TapCon fastener -- obviously, a long one (long enough to reach through the foam to the concrete).

    It's very unusual for ICFs to separate from the concrete. Can you post some pictures, and share your climate zone and local soil type?
