Sonotube® Builder's 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 Builder’s Tube concrete forms should not be used with mechanical vibrators.

Sonotube® Tube Base® footing forms are used in conjunction with Sonotube concrete forms for added strength, increased stability and greater bearing capacity. As a single piece it is easier to level, and less likely to tip, tilt or move, especially during the backfilling process. The result is lower costs due to savings in time, labor and materials.
Applications
• Decks
• Porches
• Posts
