Central Illinois | Used the same plywood forms each time, then pitched them. Now these were tall bins also, so we poured a 3' wide by 2' deep footer. Used the trench for the form on the footer, just struck off to some rebar driven into the ground at intervals. Then we ripped the plywood to 2 foot strips. We bought metal ties to hold it together, used 2X4's vertically every two feet, kicker boards on the outside, and one cable around the outside. 15 inch wide wall with lots of rebar. Worked excellent three times running. Figured it didn't owe us a thing after the last use. | |
