You can also fire up a reciprocating saw to make cleaner cuts and shave a little time off your project. [7] X Research source 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 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. Finish filling the form tube to the top. Scoop enough of the remaining concrete mix into the tube to bring it just above level. As a rule, it's a good idea to overfill the tube by about 1–2 inches (2.5–5.1 cm). When smoothed, this will create a rounded upper surface that's more attractive and encourages drainage. [13] X Research source I did the same only on a smaller scale. Used a 2 litre coke bottles, ends cut off and got 4" tubes for the top and set fischer fixings in the stiffish concrete. Stopped filling the bulk of the hole 4" below ground level, coke ring brought it level, allowed to set, and re-done to bring turf level with that.

Our Piling Tubes are ideal for many groundworks, civil engineering and piling projects. Commonly, they are just known as cardboard tubes for concrete. They are perfect to be placed on uneven ground prior to concrete being poured to ensure a level base. 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. Piling tubes are designed for use in areas where ground heave is expected, i.e. The London Clay Belt. They serve as a great foundation where the heavy weight will be applied above. A special type of industrial tube , the special slip coating allows for movement of clay around the pile, thus greatly reducing stress normally transferred through the said pile.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 source Consolidate and level the concrete. Churn the concrete thoroughly once again to prevent voids from forming in the top half of the footing. Then, smooth the surface with the flat side of your trowel. By the time you're done, the concrete should be free of lumps, depressions, or seams. [14] 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.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. An important detail is that Monotub D.D. is commonly produced to client’s specifications per project. Use a handsaw to cut the tube to length. Lay the tube on its side and line up the teeth of the saw blade with the marking you just made. Saw straight through the tube using smooth, precise strokes, steadying it with your free hand while you work. It may help to do your sawing on grass or another soft surface to keep the tube from rolling or sliding.

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. [3] X Research sourceAllow the concrete to cure for at least 24 hours. 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 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 Compact the gravel with a wood post. Use the blunt end of the post to tamp the gravel down flat. This will force the piece closer together, offering increased stability and creating a more level base. [4] X Research source 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. Monotub D.D. offers you the advantage of waterproof concrete formwork. This means it is not necessary to pour the concrete immediately after erecting the tubes.You can determine when this should be done, without the need for covering the formwork against rain, etc. Pouring the Concrete

I did something similar when the kids had a swing in the garden dug a hole filled it with concrete and use a large coffee tin about 10" dia split and held together with gaffer tape temp, to cast the above ground bit. I set some u shaped steel in the mix to bolt the tubes to. 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. 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!
