8. Sonotube form and TubeBase footing form combined cannot
    exceed/extend 24” or more above grade/ground.

9. Have inspected by building inspector as required by different municipalities.

10. Backfill making sure Sonotube form remains level/ plumbed at desired

Above grade/ground installation tips

For any TubeBase footing form project which requires the combined use of a
Sonotube form and TubeBase footing form to exceed/extend 24” above ground/grade when pouring concrete, the Sonotube form MUST be braced to
prevent movement of Sonotube form while the concrete is curing. (Conventional
methods: Strapping or 2X materials w/stakes; wooden collar; frame with side
braces)
