ICF Wall Braces Explained

As I did when I put up the basement walls, I'm installing wall bracing for the ICF walls on the main floor as well. Although the ICF blocks stack up fairly straight on their own, if you don't ensure they're tight together on both sides, or if you have any debris between them, they can get a bit out of plumb (vertically level) as the wall gets higher. By the time you get to the top of the wall, it's not uncommon for the wall to be out of plumb by up to 1/2". However, the braces allow you to bring the walls back into line before you pour the concrete. The pictures below show how they work.

In the first picture, you can see that the 2x6 studs are plumb, but there is a gap between the stud and the wall because the wall is leaning out slightly. The wall braces have a turnbuckle inside them. A few twists of the brace, and the wall is brought back to where it should be.
Now you can see that the gap is gone. The studs haven't moved, only the wall has. Now, when the concrete is poured, the braces will hold the wall plumb. Once the concrete has cured, the braces will be removed and the walls will be nice and straight.


  1. Looks like you've been doing great at ICF construction.

    The problem is getting people to find your personal icf blog or other icf blogs that are higher up than page 70 in a Google search

    I working on a site just for icf bloggers. icficf.com
    I just set it up in March based on Community server software (same as MySpace).
    Looking for ICF bloggers to contribute so ICF seekers can find us in one place.
    If you could copy your blog postings to that site it may get you more traffic and it will help launch the site.
    Let me know your thoughts.

  2. Great info! Thanks for sharing your insight on ICF construction.
