Rebar Reinforcement
Rebar is used to reinforce both the footings and foundations as well as ICF walls. Vertical rebar will be placed and extend from your foundation, footings, or stem walls and then into the walls themselves. This vertical rebar will overlap to create continuous vertical reinforcement. Make sure your rebar dowels or pins meet or exceed code requirements for wind load and backfill heights.
Ensure that rebar is correctly set in the footing and extends properly above footings for non-contact laps in walls.
Rebar inside concrete must be:
- 3 inches from any soil exposure
- ¾ of an inch from the inside face of the foam blocks
- 1½ from other faces such as bucking.
This spacing prevents moisture from intruding into the concrete and decaying the rebar. It will also provide sufficient concrete coverage for structural integrity.
