Does anyone have any idea how tall of a wall you can pour with 3/4 inch plywood forms just using cams and ties? If I make the ties close enough together does it matter? Im looking at a job that has a 16 ft tall by 90 ft wall and a 20 ft tall by 50 ft wall. Worried about possibly blowing the forms and 1 inch formboard is hard to get ahold of. Thanks!
