Do you have questions or concerns about how to install an ICF system? Even experienced builders and contractors may be unsure where to begin when exploring the technology for the first time. Until you take our training course (which we highly recommend), here is a look at the first few steps involved in ICF construction, starting out from a basement or slab on grade condition:

1. Start at the Corners
   The installer will chalk out an outline of where the building will stand, and then set the corner form ICF units in place.
   
   
2. Meet Outside Dimensions
   The standard forms will be cut to achieve the appropriate wall length, and then laid in from corner to corner. Typically, there won’t be any openings in a slab on grade condition – those will begin to form after the second course.
   
   
3. Bring in the Reinforcements
   Horizontal steel will be positioned within the form units in the cavity in preparation for reinforcing the wall.
   
   
4. Level it Off
   Once the second course is laid up, laser levels can ensure perfectly square, plumb and level walls.
   
   
5. Stack
   Place the units on top of each other. While some units are friction fit, Nudura forms use a vertical integrated interlock that holds the units solidly together along the horizontal line of the form. ICF units can be male/female (think Lego blocks) or completely reversible, with the interlocks molded into the top and bottom of forms.
   
   
6. Prepare for Windows and Doors
   As construction continues, installers will want to use a buck material to help create a rough opening where windows and doors will be set and anchored. Made of wood or steel, bucks enable the concrete to be held back and formed in the opening and can be utilized and interfaced with any ICF.
