Installation Guide

Easy steps for professional results
Place: Dig a hole to the desired depth. Place the tube in
the hole, filling around the outside to secure. If the tube
extends more than 2 feet above the ground-line, provide
additional support with a collar or wooden frame and
side braces.
Fill: Be sure the Sonotube

concrete form is
dry before filling it with concrete. Sonotube Builders Tube
concrete forms are single-use forms. It is recommended that
you erect all the tubes for your job in advance in order to
pour all at once and to save time. This reduces total
construction time and lets you enjoy your handiwork
more quickly.
Caution: Do not use a mechanical vibration technique when
placing concrete in the Sonotube Builders Tube concrete
form. To maintain the desired placement of your concrete
column, it is important that your Sonotube Builders Tube
concrete form remain stationary until the concrete sets.
Strip: Sonotube Builders Tube concrete forms are designed
to be left in place. Should you desire to strip the forms, be
sure to use a reliable release agent before pouring the
concrete. Remove the forms as soon as possible after a
24-hour curing period. Cut the forms vertically, using a
knife or power saw. (Note: no warranty is extended on
the finished concrete surface.)
Storage: If temporary storage is necessary, place tubes on
an elevated platform at least 4 inches off the ground and
cover, allowing circulation of air through the tubes.
