Product Information

Concrete Footing Tubes Cardboard tubes, fibre form tubes or tubular forms, as often referred to, can be used to form concrete into piers or pillars to act as support columns for numerous construction projects either commercially or for DIY projects around the home and garden. so i guess the good old google search i'm sure that somebody in the uk will have some but they may be hard to get! Fill the bottom of the hole with 2–6 inches (5.1–15.2 cm) of gravel. For most projects, a medium-sized all-purpose gravel will provide the best results. A layer of gravel will promote runoff, which can protect the footing from slipping or weathering and increase its lifespan.

Mark the desired depth on the outside of the form tube. Stretch a tape measure along the side of the tube and use a carpenter's pencil to draw a line indicating the depth measurement. You'll be sawing along this line to cut the tube to the right size. [5] X Research source You’ll find a range of underground drainage pipe sizes and shapes, including ovoid shape pipes and 300mm drainage pipes. Concrete drain and sewer pipes apply water flow to move freely underground. We have been supplying cardboard tubes to continental Europe where concrete is extensively used for many years. There they are utilised for producing aesthetically pleasing visible columns or for footings where they can play a valuable role in reducing labour on excavation and of course help in a cost reduction for each project. Insert the form tube into the support hole. Slide the tube in with the sawed-end down so that the upper end is straight and level. Once you've got the tube in the hole, press down firmly from the top to sink it deeper into the gravel base. [9] X Research source Dig a hole for the support. Use a post hole digger to scoop out the soil where you plan to place the footing. The hole should be slightly wider than the diameter of the form tube. Having an additional 1–2 inches (2.5–5.1 cm) of space on either side will allow you to fit the tube in without difficulty. [2] X Research sourceAn important detail is that Monotub D.D. is commonly produced to client’s specifications per project. Monotub D.D. is 100% water resistant, which means the concrete formwork can be stored outside, without the risk of damaging the quality of the column former. It is advisable to store the tubes vertically to prevent them from deforming. You can also fire up a reciprocating saw to make cleaner cuts and shave a little time off your project.

After it's had a full day to set up, the footing should be strong enough to support the weight of your building materials. If you're using a standard strength mix, it may need as long as 3 days to harden to the point where it can hold up to strain. Avoid disturbing the concrete in the meantime. [17] X Research source

confirm availability before visiting. We can also provide fast nationwide delivery of all sizes of concrete forms. Figure out how deep the support needs to sit. Refer to your local building codes to find the depth requirements for the concrete support footings of structures being built in your area. Most of the time, footings will need to reach below the topsoil frost line to prevent them from shifting as the ground freezes and thaws. You will never have the difficulties of ‘overlengths’ having to be adjusted. You will never have difficulties when ‘overlengths’ have to be adjusted. Must admit I have never seen one I assume it's just a large dia loo roll centre! If so would the carboard tubes that come inside carpets be any good they are about 4" dia? If so I'm sure a local carpet shop would be happy to get rid of one. We would use a 5 gallon plastic drum, similar to the large feb containers, cut top and bottom of, cut straight up the side, then compress it to required diameter, hold together with tying wire.

Pouring the concrete is easy with Monotub D.D. because of its strength it is possible to pour the column in one move. However, you will get the best result when the concrete is condensed after every 50 cm. With longer columns it is advisable to prevent the concrete from falling too deep, as this may cause damage to the inside of the formwork. Removing the Column Form Some building codes may also specify that the support footings for a certain type of structure be a certain diameter, which may determine the size of the form tubes you use.
