What Is the Proper Way to Field-Cut Icf Corner Forms on Site?
The proper way to field-cut ICF corner forms on site is to mark the blocks on both sides along the wall angle, cut the blocks along the marks, then properly secure the miter joint.
Using ICF corner blocks to form 45- and 90-degree wall corners is a no-brainer. But if you’ve got any unusual corners, you may be wondering how to field cut ICFs without creating unnecessary waste. Well, don’t despair — cutting ICF corner forms on site is really simple. And below, we’ll walk you through the nine steps needed to perform this procedure on your site.
9 Steps For Field-Cutting Logix ICF Blocks
Lay blocks toward the uncommon wall angle. Start the first course by laying standard blocks down from the corner block and towards the angle that requires the miter cut.
Mark the cut lines. Once you’ve laid the standard blocks, mark both sides of the forms precisely where the miter cut should be made.
Cut the blocks. Following the lines you’ve just made, cut both sides of the ICF form and discard the waste.
Cut the abutting blocks. Follow the same 3 steps we listed above on the standard block that will comprise the second part of the angle.
- Brace the newly erected blocks. The blocks you’ve just installed will need additional support around the mitered corners. To keep them in place as the concrete is poured and cured, you’ll need to install additional bracing.
- Support the blocks. Apart from bracing, you can also use sheathing or fiber tape to secure the blocks at each course. If needed, you could also resort to bracing the courses with 2-inch wood strapping.
Secure the joint. To make sure the miter joint is adequately secured, use zip ties and apply foam adhesive at the joint.
Install rebar. Following the reinforcement schedule, install rebar and secure it to the webs inside the ICFs.
Repeat for subsequent courses. For courses #2 and up, follow the same 6 steps described above.
