I am trying to make the decsion to install the Polysteel concret forms over the conventional plywood removable forms. I am will be building the plywood forms with 5/8 plywood which I would use in my floor, I would reuse the whaler board in the stud wall through out the house. I wish I could find a justificationa or cost comparison to save me that time. Any information on installed cost or time savings willbe appriciated.
