Sonotube Definition

Use our free online Sonotube calculator to get your calculations quickly. Circular forms can be an extreme hassle to create, and even more difficult to calculate in cubic yard or cubic meter measurements. Sonotubes are waxed tubes that are made from cardboard to create columns. To create the columns, concrete is used to fill in the sonotubes, providing durability and permanency.

Since concrete is sold in cubic yards, the Sonotube calculator is a very helpful and important tool that will help you ensure you purchase the right amount of concrete needed to fill the volume of the tube. This calculator is very useful if you need to calculate the measurement using Imperial measurements which uses feet units, or Metric measurements which uses meter units.

The sonotube calculator allows you to enter the following components:

  • Select calculations in cubic yards or cubic meters.
  • Sonotube Diameter
  • Sonotube Height
  • Sonotube Quantity

After submitting your figures, your calculations will appear at the top of the new page that loads after you click calculate. You may print the results and show them to a general contractor so that the correct amount of concrete materials is purchased.

The following are some important things to remember about sonotube concrete forms:

  • When building the sonotube forms, make sure that the forms are level with one another to avoid uneven or leaning columns.
  • Be sure that the forms are reinforced and secure from giving out shifting or falling apart when the heavy concrete is poured.
  • Always add more concrete than the amount calculated to account for concrete spillage and the below-ground concrete used, otherwise you may run out of concrete.
