Understanding Sonotubes
Sonotubes are cylindrical cardboard tubes used in concrete construction, primarily for forming columns and piers. The 16-inch diameter is a popular choice, offering a balance between size and structural integrity. These tubes are designed for single-use and are an eco-friendly option, as they are biodegradable, breaking down naturally when buried.
Types of 16″ Sonotubes
Standard Sonotube
The standard 16″ Sonotube is widely available and suitable for general construction needs. These tubes are perfect for creating concrete pillars that support structures. They are available in various lengths, typically ranging from 4 to 12 feet.
Removable Forms
Removable forms are engineered to withstand high pressure and can be used for more demanding applications. These are ideal for constructing permanent columns that may need to carry significant loads.
Poly-Woven Tubes
Poly-woven tubes offer unique benefits, such as resistance to vibrations during the concrete pouring process. They are lightweight, making them easier to transport and handle on job sites.
Quikrete Form Tube
The Quikrete form tube is designed for quick and easy setup. It is an excellent option for DIY projects or quick jobs where time is of the essence. With no assembly required, these tubes save time and labor.
Builder’s Tube
Builder’s tubes are suitable for high-volume concrete pours, designed to handle continuous pouring without buckling. They are often used in larger construction projects where efficiency and strength are critical.
Applications of 16″ Sonotubes
Residential Construction
In residential settings, 16″ Sonotubes are commonly used for creating footings and piers for decks, porches, and other structures. Their ease of use and reliability make them a go-to choice for homeowners and contractors alike.
Commercial Projects
For commercial construction, these tubes provide the necessary support for larger structures. Their ability to handle significant loads makes them suitable for building foundations and support columns in multi-story buildings.
Infrastructure Development
In infrastructure projects, 16″ Sonotubes are used to create pillars for bridges and overpasses. Their strength and reliability ensure that these critical structures remain stable and secure.

Best Practices for Using 16″ Sonotubes
Preparation
Before using a Sonotube, ensure the site is prepared. Clear any debris, and level the ground to provide a stable base for the tube.
Pouring Concrete
When pouring concrete into the Sonotube, follow the American Concrete Institute (ACI) recommended pour rates. This ensures the integrity of the column and prevents issues such as buckling or swelling.
Use of Release Agents
For best results, use a release agent to facilitate easy removal of the Sonotube once the concrete has set. This is especially important when using aggressive concrete formulations.
Stripping the Form
Stripping should occur within 24-48 hours after the pour. This helps to prevent the concrete from adhering to the form, ensuring a clean finish.

FAQ
What is a Sonotube?
A Sonotube is a cylindrical cardboard form used to create concrete columns and piers. It provides a mold for pouring concrete, which can then be removed once the concrete has set.
Are Sonotubes reusable?
No, Sonotubes are designed for single use. They break down naturally when buried, making them an eco-friendly option.
How much concrete do I need for a 16″ Sonotube?
To fill a 16″ Sonotube that is 4 feet tall, you would need approximately 10 x 80 lb bags or 12.5 x 60 lb bags of concrete, depending on the concrete’s yield per bag.
Can I use Sonotubes for outdoor projects?
Yes, Sonotubes are suitable for outdoor projects, such as decks and fences. However, they should not be used in applications where they will be exposed to moisture for extended periods without proper precautions.
What is the maximum height for a concrete column using a Sonotube?
While Sonotubes can support columns over 40 feet, the actual height you can achieve will depend on factors such as concrete mix and local building codes.
Do I need a release agent for Sonotubes?
Yes, using a release agent is recommended to ensure easy removal of the Sonotube from the concrete after it has set.
Where can I buy 16″ Sonotubes?
You can find 16″ Sonotubes at various retailers, including Menards, Lowe’s, and specialized suppliers like White Cap and Carl’s Building Supply.
Are there different brands of Sonotubes?
Yes, several brands manufacture Sonotubes, including Sonoco, Quikrete, and Sakrete, each offering slightly different features and specifications.
What should I do if my Sonotube buckles during the pour?
If a Sonotube buckles, you should stop the pour immediately and assess the situation. Reinforcing the form with additional bracing may help support it during the concrete pour.
Is there a weight limit for concrete in a Sonotube?
While there is no specific weight limit, it is crucial to adhere to ACI-recommended pour rates to prevent the form from buckling or deforming.
