How to Use Concrete Tube Forms

To use concrete tube forms, first measure the area where you want to place the form. Cut two pieces of 2×6 lumber to fit around each end of the form. Attach these boards to the form with screws or nails and make sure they are flush with the top of the form.

Fill in any gaps between these boards and the sides of your concrete form with caulk for a better seal. Dig a hole beneath your concrete tube to form deep enough so that its bottom is about 4 inches below ground level when placed inside it. Place gravel at least 3-4 inches thick in this hole before setting your concrete tube into it, making sure that it is square and level.

  • Gather Materials: Before you can begin using concrete tube forms, you need to make sure you have all the materials and tools needed for the project
  • This includes a level, saw, hammer drill, nails or screws, tape measure, safety glasses, and gloves
  • Prepare Site: The site where the form will be placed should be cleared of any debris or obstructions that could hinder the installation process
  • It is also important to ensure that your work surface is level before continuing with this step
  • Cut Tube Form: Depending on what type of form you are using (i
  • , round or square), use a saw to cut it into sections as needed for your project’s requirements
  • This may require multiple cuts depending on how many sections are desired for each layer of concrete poured in order to achieve its finished look once dry and cured properly
  • 4 Drill Holes For Nails Or Screws: If necessary, use a hammer drill to create holes at an appropriate depth within each section so nails or screws can be used later when securing them together inside their respective area(s)
  • Make sure these holes are evenly spaced apart from one another in order to provide adequate support while forming the shape desired within your construction design plan
  • 5 Secure Sections Together: Once all tubes have been cut and drilled accordingly, you are now ready to secure them together by either nailing or screwing them tightly along their respective edge points which should match up perfectly as long as everything was measured correctly during preparation steps prior!
How to Use Concrete Tube Forms


Do You Leave Concrete Tube Forms in the Ground?

The answer to this question is yes, you can leave concrete tube forms in the ground. This method of formwork is becoming increasingly popular for many reasons, including cost-effectiveness and ease of installation. Concrete tube forms are made from a composite material that consists of metal channels and plastic or fiberglass mesh which provides strength to hold wet concrete until it has cured.

The tubes remain in place after pouring and help create a strong structure with minimal effort from the contractor. Because these tubes are lightweight and easy to move around, they make an excellent choice for projects such as retaining walls, foundations, footings, columns, or even bridges. When using concrete tube forms in the ground there are some important things to consider – proper drainage must be taken into account so that water does not collect at the base of your structure; also ensure that any underground piping systems do not interfere with placement or pourability of your formwork; finally, check local building codes before beginning your project as there may be restrictions on how deep you can go when leaving your concrete tube forms in the ground.

How Do You Set a Concrete Tube Form?

Setting a concrete tube form is relatively straightforward; however, it requires some planning and preparation to ensure the job is done correctly. First, decide where you want your form to go and mark out the area with string or stakes. Second, dig a hole for the tube deep enough so that when filled with concrete it will reach the desired height above grade level.

Third, place a piece of reinforcing wire mesh inside of the hole before sliding in the pre-cut length of tube form. Fourth, make sure to tamp down any soil around the outside edges of your form so that no air pockets remain between it and its surroundings. Finally, fill your tube with ready-mix concrete until it reaches just above ground level – usually about 1/2″ to 3/4″.

Once set firmly in place and given adequate time to cure (usually 24 hours), you can remove your form by cutting along its sides using an angle grinder or other power tool appropriate for this type of work. Following these steps should guarantee success in setting up effective forms for pourable concrete projects!

What is a Concrete Tube Form For?

A concrete tube form is an essential tool for any construction project that involves pouring concrete. It is a cylindrical structure made of either steel or plastic that serves as a mold to pour concrete into, helping create structures like columns, footings, walls, and more. The interior of the tube form is lined with insulation to help keep the poured concrete from cracking due to temperature changes during its curing phase.

Once cured, the formed concrete can be removed from the tube form in one piece and used as part of your building’s foundation or another structural element. In addition to providing a strong base for whatever you’re constructing, using a tube form also ensures that your finished product has a uniform shape and thickness along its entire length. This makes it easier to install additional components later on if needed.

Do You Remove Sonotube After Concrete Sets?

When it comes to removing Sonotube after concrete sets, there are several factors to consider. Generally speaking, the tube should be left in place until the concrete has had a chance to fully cure. This is because the tube provides structural support and stability for the newly poured concrete while also allowing water or moisture to escape from underneath as it cures.

Once this process is complete and all of the excess water has dissipated, then you can safely begin deconstructing and removing the Sonotube from around your newly set concrete slab. It’s important to note that when doing so, you’ll want to use caution and make sure that no part of your freshly cured slab gets damaged during removal. Additionally, many contractors will fill any remaining holes with sand or gravel in order to ensure proper drainage around your new surface once everything is finished!

What Size Concrete Tube for 6X6 Post

When building a 6×6 post, the size of the concrete tube required will depend on the height and weight load that your post needs to support. Generally, for posts up to 8 feet tall you’ll need an 8-inch diameter tube with a thickness of at least 1 inch. For posts taller than 8 feet you should use a 10-inch diameter tube with a minimum thickness of 1 ½ inches.

As always, be sure to consult local codes and/or an engineer when dealing with heavier loads or higher heights.
