Wood form for 13' high poured wall?
Wood form for 13' high poured wall?
(OP)
I need to pour a concrete wall 13' high x 12' long x 2' thick. Is it possible to build a wooden form for this, or is that too much pressure? I have built forms for 8' high walls nut never anything this big.

Maximum lateral pressure for Design of Wall Forms you have at
Standard Handbook of Heavy Construction 3d ed
O'Brien, Havers, Stubbs Jr.
Mc Graw Hill
Table C1-21 at p. c1-97
Then dimension the wood elements, and and shores for your code. For classical dimensioning of wood elements I have sheets of free download for Mathcad 2000 Pro in the Collaboratory site at Mathsoft.

You will need to space the Snap-Ties closely so that you don't get a "pillow" effect in the wall from deflection of your plywood form. Use MDO plywood, if you can get it.
Be sure to anchor a 2x member at the bottom to prevent blow-out, and at each plywood joint.
