Step 1

SquareFoot™ and construction tube.

Step 2

Cut off excess plastic at top of wedges to desired construction tube size.

Step 3

Saw construction tube to desired length.

Step 4

Attach construction tube to SquareFoot™ footing form with a minimum of 4, 1“(2.5cm)screws.

Step 5

Excavate hole to a depth to avoid frost penetration under pier (Typically 5'(1.5m)).

Step 6

Place SquareFoot™ and construction tube on undisturbed soil or 4"-6"(10cm-15cm) of compacted crushed stone or gravel.

Step 7

Place SquareFoot™ footing form at desired location.

Step 8

Level/plumb construction tube/SquareFoot™ footing form prior to backfilling.

Step 9

Construction tube and SquareFoot™ footing form combined cannot extend 36" (91cm) or more above ground line/grade without being braced.

Step 10

Backfill using shovel or backhoe.

Step 11

Backfill making sure construction tube remains level/plumbed at desired location.

Step 12

Invert spare SquareFoot™ on top of construction tube to act as a funnel prior to concrete pour.

Step 13

Pour concrete in the top of inverted SquareFoot™.

Step 14

Remove the funnel and spray SquareFoot™ off. Trowel concrete.

Step 15

Install anchor bolt to accept bracket as required.

The small vent holes in the sloped sections allow the escape of air trapped inside the footing form when the footing is being poured with concrete.
The top rings of the SquareFoot™ footing forms are designed to accept various inside diameter construction tubes from various manufacturers for each footing form model. The rings not used must be cut off at the top of the ring being used and removed before any concrete is poured.
The bottom base flange is designed to fit flat on the excavated area and provides a location at the base where 3/8" (0.95cm) of 12 - 12" (30.50cm) steel spikes may be drilled on at a 45 degree inward angle. This will anchor the footing form in position for above ground use or when the unit has not been backfilled.
