Depend on Sonotube quality.

most economical way to create columns for buildings, and to
provide structural support and footings.
Working with Sonotube Builders Tube
concrete forms
Sonotube Builders Tube concrete forms are built strong to
withstand the heavy pressure of wet concrete. The one-of-a-
kind Sonotube Builders Tube concrete form is designed for
below ground-line concrete placement, but can be used up to
3 feet above ground-line for extra support. Minimal bracing is
required above 2 feet of ground-line.
Sonotube Builders Tube concrete forms are not designed to be
stripped from the cured concrete. If stripping above ground is
desired, use a releasing agent before pouring the concrete and
remove as soon as the concrete is set. Sonotube Builders Tube
concrete forms should not be used with mechanical vibrators.
