The panels and fillers may be used on either the inside or outside of the wall.  The standard 16" waler bar spacing allows all them to be aligned vertically side-by-side for “step-ups” as well as stacking for higher walls.

These durable forms are constructed from eleven ply, 1-1/8 inch, Structural I grade plywood with a 100/100 HDO overlay for consistent strength and quality.

These panels can also be lined with Form Liners.
