Concrete Forms


1 1/8”, structural 1 grade forming plywood made of 100% Douglas Fir with 11 plys for added strength and durability. Duraform was the first to offer chamfered edges and an improved edge seal. DURAFORM® Concrete Forms are efficient and accurate – saving both time and money!

Available in standard bar spacing options or customized to fit your needs, DURAFORM
® Concrete Forms will outperform the competition pour for pour.

2’ Stacking panels are used when additional height is required above a DURAFORM
® Panel. Example: 10’ walls are achieved by using our 8’ form, with a 2’ stacker panel, 6’ walls are achieved by using our 4’ form with a 2’ stacker panel. Stacking panels are set best when vertical 2x4’s are placed on one side of the wall on approximately 12” centers. Strongback clamps are recommended for this application.
