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.
Homemade plywood concrete wall forms.
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.
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.
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.
Nearly all types of plywood panels can be used in concrete forming from common roof and wall sheathing to sanded panels.
Snap tie concrete forms are a simple and easy system for foundation walls.
Worried about possibly blowing the forms and 1 inch formboard is hard to get ahold of.
Then pour your concrete inside the form using a chute or hose attached to the mixer.
The plywood needs to be of forming quality.
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.
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.
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.
If they will be reused then use treated lumber.
The form will be lightweight and strong.
2 x 4 s and 3 4 forming plywood works best.
