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! 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.

You can also fire up a reciprocating saw to make cleaner cuts and shave a little time off your project. [7] X Research source 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 sourceWe 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. 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

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. 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. 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 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.

EUH208 - Contains reaction mass of 5-chloro-2-methyl-2H-isothiazol-3-one and 2-methyl-2H-isothiazol-3-one (3:1) An important detail is that Monotub D.D. is commonly produced to client’s specifications per project. Search by state, province, or territory to pull up a copy of your local building codes online.

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.

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. 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 source 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. 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 You will never have the difficulties of ‘overlengths’ having to be adjusted. You will never have difficulties when ‘overlengths’ have to be adjusted.

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. This reduced the amount of excavation needed and also reduces the time taken, being both cost and time effective.
