Bigfoot footing forms are best - compare the difference!
Round Bigfoot System® or square wooden box?

A key Bigfoot advantage rests with its shape - a bell shaped footing with a round base - which uses the natural laws of physics to evenly distribute the entire load's weight, solidly securing the footing to the earth, something a square footing just cannot do.

In the words of engineer Doug Steadman, PEng, Texas, USA: "The bell footing was developed through trial and error and proven mathematically and scientifically to provide greatly increased stability when the foundation is on suitable bearing material. This has been extensively documented since the early 1920s, and now a routine part of engineering practice design."
