Bags Of Concrete Per Sonotube Chart
To determine the number of bags of concrete you will need to fill a Sonotube, you will need to know the size of the tube, the strength of the concrete mix, and the volume of the bag. You can use the following formula to calculate the number of bags you will need:
Number of Bags = Volume (in cubic yards) x Strength (in psi) / Bag Volume (in cubic feet)
Here is an example of how you could create a chart using this formula: To use this chart, you would need to determine the size of the Sonotube you will be using, the strength of the concrete mix, and then look up the corresponding number of bags in the chart.
For example, if you are using a 24-inch Sonotube and a concrete mix with a strength of 3,000 psi, you would look in the chart and see that you will need X bags of concrete.
Keep in mind that this is just a rough estimate and the actual number of bags you will need may vary based on factors such as the concrete’s moisture content and the mix’s density. It is always a good idea to purchase a few extra bags of concrete just in case you need them.
How To Use A Sonotube?
Sonotube is a brand of cardboard tubes that are often used in construction to form the foundations of buildings. These tubes are designed to be filled with concrete to create a solid, stable foundation for a structure. If you are planning to use Sonotube for your next construction project, here is a step-by-step guide on how to use it:
Step: 1. Determine the Size of the Sonotube:
The first thing you will need to do is determine the size of the Sonotube you will be using. Sonotube comes in a range of sizes, from 12 inches in diameter to 36 inches in diameter.
The size you choose will depend on the weight and height of the structure you are building, as well as the soil conditions at the site. It is important to choose a size that is appropriate for your needs to ensure that the foundation is strong and stable.
Step:Â 2. Calculate the Volume of the Sonotube:
Once you know the size of the Sonotube, you can calculate the volume of the tube using the following.
Formula: volume = πr^2h,
Where r is the radius of the tube and h is the height of the tube.
This will give you the total volume of the Sonotube in cubic feet.
Step: 3. Convert the Volume to Cubic Yards:
To make it easier to calculate the number of bags of concrete you will need, you will want to convert the volume of the Sonotube from cubic feet to cubic yards. To do this, divide the volume in cubic feet by 27 to get the volume in cubic yards.
Step: 4. Determine the Strength of the Concrete Mix:
The next step is to determine the strength of the concrete mix you will be using. Concrete mixes are rated by their compressive strength, which is measured in pounds per square inch (psi).
The higher the psi rating, the stronger the concrete. A concrete mix with a compressive strength of at least 3,000 psi is recommended for most foundation projects.
Step: 5. Calculate the Number of Bags of Concrete Needed:
Once you have the volume of the Sonotube in cubic yards and the strength of the concrete mix, you can use the following formula to calculate the number of bags of concrete you will need:
number of bags = volume (in cubic yards) x strength (in psi) / bag volume (in cubic feet)
For example, if you have a Sonotube that is 18 inches in diameter and 10 feet tall (with a radius of 9 inches and a volume of 1.5 cubic yards), and you are using a concrete mix with a strength of 3,000 psi, you will need approximately 56 bags of concrete.
Step: 6. Prepare the Site:
Before you begin working with the Sonotube, you will need to prepare the site where it will be placed. This includes clearing the area of any debris, grading the ground to ensure it is level, and compacting the soil to reduce the risk of settling.
Step: 7. Set the Sonotube in Place:
Once the site is prepared, you can set the Sonotube in place. To do this, you will need to dig a hole that is slightly larger than the diameter of the tube. The hole should be deep enough to allow the top of the Sonotube to be level with the ground when it is filled with concrete. Place the Sonotube in the hole and use wooden stakes to hold it in place.
Step: 8. Fill the Sonotube with Concrete:
Once the Sonotube is in place, you can begin filling it with concrete. Mix the concrete according to the manufacturer’s instructions and pour it into the Sonotube using a wheelbarrow or concrete mixer.

Step: 2. Calculate the Volume of the Tube:
Once you know the size of the tube, you can calculate the volume of the tube using the following
Formula: volume = πr^2h,
Where r is the radius of the tube, and h is the height of the tube.
This will give you the total volume of the tube in cubic feet.
Step: 3. Convert the Volume to Cubic Yards:
To make it easier to calculate the number of bags of concrete you will need, you will want to convert the volume of the tube from cubic feet to cubic yards. To do this, divide the volume in cubic feet by 27 to get the volume in cubic yards.
Step: 4. Determine the Strength of the Concrete Mix:
The next step is to determine the strength of the concrete mix you will be using. Concrete mixes are rated by their compressive strength, which is measured in pounds per square inch (psi). The higher the psi rating, the stronger the concrete.
Step: 5. Calculate the Number of Bags of Concrete Needed:
Once you have the volume of the tube in cubic yards and the strength of the concrete mix, you can use the following formula to calculate the number of bags of concrete you will need:
number of bags = volume (in cubic yards) x strength (in psi) / bag volume (in cubic feet)
For example, if you have a tube that is 18 inches in diameter and 10 feet tall (with a radius of 9 inches and a volume of 1.5 cubic yards), and you are using a concrete mix with a strength of 3,000 psi, you will need approximately 56 bags of concrete.
It is important to note that this is just a rough estimate and the actual number of bags you will need may vary based on factors such as the moisture content of the concrete and the density of the mix. It is always a good idea to purchase a few extra bags of concrete just in case you need them.

Do I Need Rebar Inside A Sonotube?
It is generally recommended to use rebar inside a Sonotube when filling it with concrete to create a foundation for a building or other structure. Rebar, or reinforced steel bar, is used to strengthen and reinforce concrete structures. When used inside a Sonotube, rebar helps to increase the tensile strength of the foundation and reduce the risk of cracks or other structural damage.
There are a few different ways to use rebar inside a Sonotube. One common method is to place vertical rebar every 2 feet around the circumference of the tube.
This helps to hold the concrete in place and prevent it from cracking under the weight of the structure. Another option is to use horizontal rebar, which can be placed every 2 feet along the length of the tube. This helps to distribute the weight of the structure evenly across the foundation.
In general, it is recommended to use at least #4 rebar (which has a diameter of 1/2 inch) when reinforcing a Sonotube foundation. However, the specific size and placement of the rebar will depend on the size and weight of the structure, as well as the soil conditions at the site.
It is important to note that using rebar inside a Sonotube is not required in all cases. For smaller structures or structures that are not subjected to heavy loads, it may be possible to use concrete alone without the need for rebar. However, in most cases, using rebar is a good idea to ensure the stability and strength of the foundation.
Should I Use Gravel At The Bottom Of A Sonotube?
Using gravel at the bottom of a Sonotube can be a good idea in certain situations, as it can help to improve the stability and strength of the foundation. When used in conjunction with concrete, gravel can help to create a more solid and durable foundation that is less prone to settling or cracking.
There are a few different ways to use gravel at the bottom of a Sonotube. One common method is to fill the bottom of the tube with a layer of gravel before adding the concrete.
This helps to distribute the weight of the structure evenly and prevent the concrete from sinking into the ground. Another option is to use gravel as a base for the Sonotube, placing the tube on top of a layer of gravel before filling it with concrete.
The specific type and size of gravel you use will depend on the size and weight of the structure, as well as the soil conditions at the site. In general, it is recommended to use a layer of gravel that is at least 4 inches deep. Larger stones, such as 3/4 inch or 1 inch in diameter, are often used for this purpose.
It is important to note that using gravel at the bottom of a Sonotube is not required in all cases. For smaller structures or structures that are not subjected to heavy loads, it may be possible to use concrete alone without the need for gravel. However, in most cases, using gravel can help to improve the stability and strength of the foundation.
Should A Sonotube Be Filled To The Top?
It is generally recommended to fill a Sonotube to the top when using it to create a foundation for a building or other structure. This ensures that the foundation is strong and stable and can support the weight of the structure.
When filling a Sonotube, it is important to use the correct amount of concrete to ensure the foundation is strong enough to support the structure.
To calculate the amount of concrete you will need, you will need to know the size of the tube, the strength of the concrete mix, and the volume of the bag. You can use the following formula to calculate the number of bags of concrete you will need:
Number of bags = volume (in cubic yards) x strength (in psi) / bag volume (in cubic feet)
Once you have the correct amount of concrete, you can fill the Sonotube to the top, making sure to tamp the concrete down firmly to remove any air pockets. It is important to fill the tube as uniformly as possible to ensure that the foundation is evenly supported.
It is also a good idea to use rebar, or reinforced steel bar, inside the Sonotube to help strengthen and reinforce the foundation. Rebar can be placed vertically or horizontally inside the tube, depending on the size and weight of the structure.
In conclusion, it is generally recommended to fill a Sonotube to the top when using it to create a foundation. This helps to ensure that the foundation is strong and stable and can support the weight of the structure.
