Note: It is strongly recommended that anyone building a structure with ICFs receive the proper training and consultation before starting any project.

Footings:

• If the ICF bracing system cannot be used on the interior walls, make sure the foundation is excavated so that there is ample room for the bracing system to be utilized on the exterior of the wall.
• Prepare for the wall depth, width and amount of rebar for the footing in accordance with state or engineering specifcations for correct wall, floor and roof loads.

First Course:

• Use a chalk line to mark the footings where the forms are to be laid.
• Glue the first course of the forms to the footing, using appropriate foam gun with Foam-2-Foam adhesive.
• Continue stacking the forms, making sure that the plastic form ties are stacking correctly and that the wall is being erected plumb.
• Never build an ICF wall higher than 12 feet per concrete pour.

Bracing:

• Use only the manufacturer's recommended ICF bracking systems.
• Start utilizing the bracing once the third and fourth courses of the wall are installed.
• Once the bracing is set, the builder can reach to the height of the wall by using the scaffolding system incorporated with the bracing. In addition, the wall is now safe from wind gusts or high winds that could possibly move the wall.
• Always consult with the distributor and/or manufacturer for correct bracing procedures.

Rebar:

For the Walls -

• Use only state or the manufacturer's engineered recommendations for horizontal and vertical rebar placement in the wall.

For Lintel Openings -

• Use only state or the manufacturer's engineered recommendations for any openings that are incorporated in an ICF wall.

Concrete Pours:

• Always follow the distributor's and/or manufacturer's pre-pour checklist prior to pouring and ICF wall.
• Pour the wall in 4 foot lifts. Never pour an ICF wall to the top of the desired wall height in one lift.
• Use a concrete mix of 3,500 psi with a slump between 4-6 inches. When building with 4-inch ICFs, use only a 3/8" aggregate mix for better concrete flow.
• When the pour is complete, re-check and straighten the ICF walls as needed.
• Place anchor bolts for the sill plate, or place dowels for the next level of ICF forms to be installed.
