Vertical Rebar

Now that the ICF walls are up, I can install the vertical rebar. When the ICF walls are being built, rebar is layed horizontally in each row of blocks. The photo below shows how the alternating rows of horizontal rebar are placed in different slots in the interior web. This allows for the vertical rebar to be dropped in from the top, and woven between the horizontal rows. This keeps the vertical rebar in place when the concrete is poured.

The only physical connection that's required is at the top of the walls, where the vertical rebar is tied to the horizontal rebar with cable ties.
