Sono tubing (also known as Sona tube or sonde tube) is a type of plastic tubing used in horizontal directional drilling (HDD). It is designed to protect electrical cables and LVAC lines as they are installed under roads and various other surfaces.
It is usually made from PVC or polyethylene. Sono tubing comes in a range of sizes to fit various cable types and installation requirements. The length of the tubing typically varies between 5 and 100 meters, allowing for deeper installation and longer cable runs.
It can be used in a variety of applications, such as telecommunications, water, power, and gas distribution. The tubing also offers protection against water, dust, and other contaminants that can damage or distort signals.
Sono tubing is an effective and cost-efficient method of laying cables and LVAC lines below ground, saving time, money and effort.
How do you use sonotube foundation?
Sonotube foundations are an easy and cost-effective way to build a sound foundation for home and small commercial building projects. They are made from a thick, ridged cardboard tube and filled with concrete to create a stable foundation for columns, poles, and posts.
To begin a sonotube foundation, the area for the foundation must be excavated to an appropriate depth relative to the frost line, typically 18″ to 48″ depending on region. After ensuring that the location and depth are correct, the sonotube is then inserted into the excavated area, and held in place with a stake or two around the perimeter.
The tube should be cut so that it can either be slightly above or flush with the finished grade.
Once the sonotube is inserted and aligned at the appropriate elevation, the tube is then filled with concrete and tamped down. To ensure an even flow of concrete, an internal vibrator should be used as it is poured in.
This may require additional assistance as the entire length of the tube needs to be filled in a timely manner.
Once the concrete is poured and tamped, the sonotube foundation should be allowed to cure for at least 24 hours or per the manufacturers recommendation. After the foundation has cured, it can be cut or capped off to the desired elevation.
The tube and stake can then be removed, revealing the completed sonotube foundation.
How much does Sono tube cost?
The cost of Sono tube depends largely on the size of the tube, the type, and the quantity you need. Generally, 8-inch diameter Sono tube runs around $30 for a 10-foot section. For larger diameters, the cost usually goes up.
An 18-inch diameter Sono tube typically costs about $90 for a 10-foot section. The cost can also vary depending on where you purchase the Sono tube and if you order a large quantity. Generally, large home improvement and hardware stores will have the best prices for Sono tube.
How do you hold a sonotube in place?
Sonotube concrete forms can be held in place by staking them into the ground. Staking involves inserting two stakes – one on each side – into the ground, probably a few inches away from the Sonotube form.
To secure the stakes, you should use a hammer, being careful not to damage the tube. You should also ensure that the stakes are firmly in the ground so that the form will remain stable and not be affected by shifting or movement.
You can also use string or other tying materials around the stakes to secure the form even further. If the Sonotube is supported by another structure, such as a wall, it can be secured with brackets.
The brackets should be attached to the wall and Sonotube form and then tightened with screws or bolts to ensure the form is firmly secured. If the Sonotube is not supported by anything, it will need to be filled with concrete for extra stability.
What is the purpose of a sonotube?
A sonotube is a large circular cardboard form used in construction and concrete pouring. The purpose of a sonotube is to help create a strong, durable and uniform foundation when pouring concrete. Sonotubes are designed to have a high compressive strength and stiffness that allows them to withstand the weight of concrete, while also reducing any settling or cracking of the concrete once it has been poured.
Another advantage of the sonotube is the relatively easy setup and tear down process when compared to other foundation options. Sonotubes can be used for a wide variety of projects including decks, patios, retaining walls, and concrete footings.
They are also often used for motorcycle, RV and shed foundations. Additionally, sonotubes save time, reduce labour costs and provide a uniform and secure foundation when pouring concrete.
Do I need to put rebar in sonotube?
The use of rebar in a sonotube depends on the specific application. In general, when pouring an underpinning, footing, or other foundation element that is exposed to significant load or stress, rebar should be used to help create a stronger concrete structure.
Rebar can help maintain the shape of the concrete in the sonotube, prevent cracking and reduce shrinkage around the shape of the sonotube. In some cases, the use of rebar is also specified in local building codes.
Even when local codes do not require the use of rebar in a particular application, rebar is generally recommended to ensure a strong foundation. It is best to talk to a structural engineer or contractor to determine the specific requirements for your particular application.
How do you remove sonotube after pouring concrete?
Removing a sonotube after pouring concrete is a relatively straightforward process. First, you will want to allow the concrete to cure for a few days before attempting to remove the sonotube. This will ensure the concrete has had sufficient time to set and harden.
Once the concrete has cured, you can begin the removal process.
Start by loosening the top of the sonotube. You can typically use a hammer and a chisel to do this. Once the top is loose, you can pull it out. If the tube is still stuck, you can use a circular saw to cut the sonotube into smaller pieces and remove it in smaller chunks.
When removing sonotubes, you need to be careful that you don’t damage the concrete. Use caution when using the saw and try to cut as straight and cleanly as possible. Once the sonotube has been removed, check the surface of the concrete.
If any inconsistencies are noticed, you can repair them by using concrete patching material. Finally, use a shop vac to clear any debris left behind by the sonotube.
How do you set up deck Sonotubes?
Setting up deck Sonotubes generally involves preparing the ground, prepping the area to which the tubes are being attached, and then fitting the Sonotubes in place.
First, if the Sonotubes are going to be secured in soil, you need to prepare the ground by removing any vegetation or objects, and leveling the surface. After that, you may need to dig a trench in the soil and fill it with gravel.
This process should create a stable, solid foundation to which the Sonotubes can be attached.
Once the ground is ready, the next step is to prep the area to which the Sonotubes are being attached. Use a level and a string line to mark off a straight line, and then use a saw to cut grooves along the marked line.
These grooves will help to secure the Sonotubes in place.
Finally, fit the Sonotubes against the marked line. Connect the Sonotubes together with steel anchors and a hammer drill, or use construction adhesive to bond them together. Once the Sonotubes are secured in place, pour concrete and let it set before adding any decking.
Once the concrete has set, use a saw and drill to install posts and beams, and then attach decking and any other components needed to complete the deck. Ensure that all connections are appropriately tightened and secure.
How many 80lb bags of concrete does it take to fill a 12 sonotube?
It depends on the size of the sonotube you’re using, but an average 12″ sonotube will take around 17 80lb bags of concrete to fill. This will provide a 3″ concrete thickness and should be enough to perform most residential or small project jobs.
You may want to consult a concrete expert to be sure about your needs for a particular project. It’s important to note that bags of concrete do not always contain the weight indicated on the bag, and that most manufacturers only guarantee 80% of the stated weight, so it’s best to plan for a few extra bags just in case.
How deep should sonotube be?
The depth of a sonotube depends on several factors, including local building codes and requirements, the soil conditions on the site, the purpose for which the tube is being used, and other considerations.
Generally, 6 to 8 feet is a good depth for an average-sized sonotube. However, it’s important to consult a licensed structural engineer to determine the appropriate depth for your particular project.
Additionally, soil conditions may require additional depth or stability features, such as ground anchors or a concrete footing, which can add additional depth. Foundations for homes, for instance, require a minimum depth that often exceeds 8 feet.
The depth of the sonotube will also likely vary depending on when the excavation is to be completed. If the tube needs to be completed in a shallow area, the excavation will need to be deeper than if it were in an area with higher ground levels.
Finally, the weight of the structure you plan to build will provide some guidance in the sonotube’s depth. The greater the load, the deeper the sonotube will need to be.
Can you leave sonotube in the ground?
Yes, it is possible to leave sonotube in the ground, depending on what your intended purpose is. Sonotube is a type of concrete form made out of cardboard, which is often used to pour concrete in deep holes or foundation piers.
If you are using it for a foundation, it is recommended that you fill the sonotube with concrete and then leave it in the ground as part of the permanent foundation structure. In this case, you would need to ensure that the concrete is allowed to cure properly before moving on to the next step.
However, if you are simply using the sonotube to pour a hole in the ground, such as a septic, water, or drainage system, then it is possible to remove the sonotube after you have filled it with the desired material.
This is assuming that you plan to backfill the hole with dirt and not leave the concrete exposed. In this scenario, you may want to reinforce the hole with steel rods or other structural materials before you backfill with soil.
In any case, it is important to consult with a professional engineer or contractor to make sure you are building your project safely and properly.
Does a sonotube need a footer?
Yes, it is highly recommended to include a footer when using a sonotube. The reason for this is that sonotubes are primarily made from a corrugated paper material wrapped in plastic, and this material is not strong enough to support a structure on its own.
A concrete footer helps to distribute the weight of the structure across the entire area, which helps to ensure structural integrity of the entire building. In addition, the footer acts as a barrier between the soil and the structure, to prevent any movement of the soil underneath the structure.
The footer also serves to anchor the building securely in the ground so that it can better withstand high winds and seismic activity. For best results, the footer should be at least 6 inches thick and should extend out at least 6 inches beyond the radius of the tube.
Do you need to remove concrete form tube?
Yes, concrete form tubes need to be removed once the concrete has had sufficient time to dry and cure. This typically should occur in an area that has plenty of ventilation and is out of direct sunlight to ensure that the concrete is not exposed to any extreme temperatures or other conditions.
Depending on the specific concrete product being used, the amount of time required for curing can vary. However, typically, concrete curing can take between 7 and 28 days to achieve full strength. It is important to ensure that concrete form tubes are removed during this curing period in order to avoid any hindrance with the curing process and to prevent any blockages in the tubes themselves.
Additionally, after removal, tubes will need to be inspected for any imperfections, cracks, or other damaged that may have occurred during the curing process. If any damage is noticed, the tubes may need to be repaired or replaced in order to maintain the structural integrity of the concrete and the formwork.
Can Sonotubes get rained on?
Yes, Sonotubes can get rained on without any adverse effects. They are made from sturdily constructed corrugated cardboard, which is weatherproofed with a special wax coating. This coating is designed to keep water out, so that it won’t damage the tube or any of the contents that may be stored in/on them.
Additionally, the tube’s shape helps to disperse rainwater, ensuring that it won’t pool up and seep into the tube. Sonotubes are designed to be highly durable and reliable, making them a great option for outdoor projects or those in areas subject to high rainfall or water exposure.
Can you backfill Sonotubes before pouring concrete?
Yes, it is possible to backfill Sonotubes before pouring concrete. The process is simple and can be done using backfill material such as crushed stone, sand, and pea gravel. Backfilling prior to pouring ensures that the cement walls of the Sonotube are not damaged while they are being filled.
Additionally, backfilling with the appropriate material can improve the strength and stability of the Sonotube.
The backfilling process first requires the Sonotubes to be secured in place. This is done by digging a trench or installing ground stakes to help hold the tubes in place before the concrete is poured.
Once the Sonotubes are securely in place, the area around them should be cleared of any large rocks, roots, or other debris that may interfere with the backfilling process. Once the area is cleared, the backfill material should be placed inside the Sonotube, a foot or so at a time, using a shovel or trowel.
The material should be compacted in layers with a tamper or a hand-held compaction tool. The compacted material will provide a stable base for the concrete once it is poured.
The backfilling process should be done carefully and in exact accordance with the manufacturer’s instructions to ensure the Sonotubes are properly prepared for the concrete. Once the backfill is complete, the concrete can be poured, ensuring a strong and stable foundation for any structure built on top of it.
How much concrete do I need to fill a 10 inch sonotube?
You will need to calculate the volume of concrete that the 10 inch sonotube will hold to determine the total amount of concrete you will need to fill it. To do so, you need to first determine the diameter of your sonotube, which is 10 inches, and then calculate the circumference of the tube.
You can use the equation π x diameter = circumference, so for a 10 inch diameter, your circumference will be 31.4 inches. You will then need to calculate the volume; you can use the equation circumference x length = volume, so for a 10 inch diameter and desired length of the tube, that would be 31.
4 inches x the length desired. The calculation will be in cubic inches, so you will need to convert the figure to cubic feet by dividing the total number by 1,728. The volume you have determined will be the total amount of concrete you need to fill the 10 inch sonotube.
