How do I brace this form?
Secure 2x4 to the footing on both sides of the Form to hold the bottom of the panel in place. Then use 2x4’s connected across the top of the FORM with a metal strap to hold the top of the wall steady. Use vertical 2x4’s, every 6’ along the wall with a horizontal 2x4 attached every 4-6’ from bottom to top of wall as illustrated in the directions. DO NOT SCREW ANY OF THE 2x4’s TO THE FORM!
Can you add rebar to this form?
You can add rebar to the form in the vertical and horizontal direction just like any other concrete wall form. Use short corner sections at the corners and overlap the corresponding rebar from either direction. The rebar can lay in the center of the form at the bottom of every fourth circle cut out. Overlap the rebar according to ACI 318.05 and ACI 318.11. Consult your local engineer for the proper rebar specifications and follow recommendations.
