Bigfoot Installation Guides:

Below grade footing form installation

For below grade applications simply attach the sonotube footing form to the construction tube with a minimum of four screws, place in the ground on top of undisturbed soil, or on 4" to 6" of compacted crushed stone or gravel, level, plumb and backfill. Use another footing form turned upside down as a funnel for pouring concrete into the tube.

Above-ground precast concrete footing installation

For above ground applications, simply attach the required length of construction sonotube to the footing form with a minimum of four screws. Drill 3/8" (10mm) holes on a 45 degree angle in the footing form as indicated by the markings on the flange area at each rib location to accept a minimum of 12" (30cm) spikes.

Place the sonotube footing forms on undisturbed soil and drive spikes at a 45 degree angle inward so as to prevent the footing form from rising when concrete is being poured. Use another footing form turned upside down as a funnel for pouring concrete into the tube.
