Bigfoot Systems BF36 36 in. Footing Form Base (Fits 12 in. – 18 in. Tubes)

The Bigfoot Systems BF36 footing form is a pre-engineered, bell-shaped concrete footing form for commercial and industrial pier foundations. It connects to standard 12-inch, 14-inch, 16-inch or 18-inch construction tubes to create a stable spread footing and concrete pier in a single pour. It is designed for large decks, timber-frame structures, commercial buildings, industrial projects and other high-load applications.

Features and Benefits

• Pre-engineered footing form replaces traditional site-built wooden footing boxes
• Bell-shaped design helps distribute structural loads over a wider area
• Structural ribs add strength while integrated air vents support proper concrete placement
• Sheds water away from the footing area
• Helps resist uplift and frost movement when correctly sized and installed
• Lightweight construction makes it easier to transport, position and install
• Remains in place after the concrete is poured

Important: The 6 cu. ft. concrete volume applies to the BF36 footing form only and does not include the attached construction tube. Total concrete requirements depend on the tube diameter and length. Confirm the required footing size, load requirements and frost depth with your local building authority and install according to the current Bigfoot Systems instructions.
