Bigfoot Systems® Footing Form is an engineered designed footing form made from recycled high density polyethylene which replaces the wood formwork. The footing form is cone-shaped with an allowance for standard fibre construction tubes to be attached to the top of the footing form. The Bigfoot Systems® Footing Form may be back-filled and is then filled with concrete to create a monolithic pour which forms the footing and pier as one unit. The construction tube and footing form remain in place after the concrete is cured. Use with 8" and 10" tubes. An easy way to use casing product for your concrete construction tube footings.
