If you live in an area that receives high annual rainfall, pour the gravel a little thicker to prevent water from pooling at the base of the footing. Another really good solution are conical "big foot" plastic sleeves that are simply dropped into a hole and filled with concrete with an embedded threaded bar for fixing. A layer of gravel will promote runoff, which can protect the footing from slipping or weathering and increase its lifespan.

You’ll find a range of underground drainage pipe sizes and shapes, including ovoid shape pipes and 300mm drainage pipes. This will force the piece closer together, offering increased stability and creating a more level base. I beleive they use carboard tubes in NZ to form round columns maybe up to 10 feet high, they must be strong and I suppose they will be waterproofed on the inside, my old mate there had columns suporting a walkway around his house and they were at least 8 foot high, you could see the spirall of the cardboard impressed on the outside surface.

Saw straight through the tube using smooth, precise strokes, steadying it with your free hand while you work. You can also fire up a reciprocating saw to make cleaner cuts and shave a little time off your project. After digging a hole in the correct dimensions for the support, slide the form tube into the hole and fill it with concrete, making sure the concrete mix is properly consolidated to eliminate air pockets and other defects.

The mouth of the pile needs no extra support during pouring and will not expand under loading, unlike plastic tubes. Storage on site can be done without the risk of damaging the quality of the formwork because of humidity or rain.It may help to do your sawing on grass or another soft surface to keep the tube from rolling or sliding. They then put a metal bracket on top that is used to hold the bottom of a wooden post in place to build the decking on. 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.
