The plywood needs to be of forming quality.
Homemade plywood concrete wall forms.
2 x 4 s and 3 4 forming plywood works best.
Apa plyform panels however are specifically designed to withstand the wear and tear of repeated concrete pours as well as to provide a smoother and more consistent finish to the concrete s surface.
Im looking at a job that has a 16 ft tall by 90 ft wall and a 20 ft tall by 50 ft wall.
Cut your plywood accordingly.
To make the wall as strong as possible pour the concrete in layers no higher than 20 inches working from 1 end of the wall to the other.
A do it yourselfer can pour concrete between 2 by 4 forms when installing a new sidewalk or patio but for best results pretreat the wood in the same way the pros do.
You want your wood to be as tall as your planned wall but to form the width the length of the wall using at least 4 foot sections.
The form will be lightweight and strong.
Nearly all types of plywood panels can be used in concrete forming from common roof and wall sheathing to sanded panels.
Does anyone have any idea how tall of a wall you can pour with 3 4 inch plywood forms just using cams and ties.
To form a concrete wall first set up plywood boards on either side of your concrete footer and attach them together with wire.
If they will be reused then use treated lumber.
Worried about possibly blowing the forms and 1 inch formboard is hard to get ahold of.
The 2 x 4 s should be no 2 kiln dried pine simply because it is cheap easy to work with and holds nails very well.
