Sonotube Square Concrete Forms Installation Guide

How to store

Store Sonotube square concrete forms in a dry place at the job site:

• For best results, store forms vertically to maintain roundness.
• Keep ends covered at all times.
• If stored horizontally, elevate a minimum of 4 inches off the ground and
  support the full length of the forms.

Placing

Even the largest Sonotube brand concrete forms are easier to place either manually with block and tackle, or by crane:

• Position over a reinforcing bar cage if desired.
• Avoid damaging the inside surface.
• Place individually or in groups for continuous pouring.

Bracing

Sonotube square concrete forms require minimal bracing to be brought to plumb:

• Use light lumber or scaffolding.
• Secure the column foot with collars if necessary.
• If pouring bents for bridges, consider tying the column form in with the beam
  form. Sonotube concrete forms can also be tied into other forms or
  structural members.

Pouring

NOTE: Use a release agent with all Sonotube concrete forms, especially when working with aggressive concrete formulations.

Sonotube concrete forms are engineered not to buckle, swell or lose shape, and have been successfully used with a continuous pour of columns well over 40 feet. Do not exceed ACI-recommended pour rates.

Concrete must be vibrated during pour.

Stripping

If stripping is required, strip the form as soon as possible after the concrete has set to prevent concrete from sticking to the form. Recommended time for the easiest and fastest stripping is 24 to 48 hours after the pour. Sonotube concrete forms should not be left on the column for more than five days.

Stripping procedure:

• Detach the RipCord stripping filament at the top of the form and wrap around
  a hammer or other tool handle.
• Pull strap straight down from the top of the form to tear through the form wall
  and remove the form. Stripped forms can be used to protect finished columns
  until completion of project.
