you are going to help me SOO much when i get older with these videos. so that i cant do home improvement properly like you. :D

[Matthiaswandel]

Not exactly "proper" how I fixed it, but it will hold for five years, and then I'll think about it again.

Wouldn't all these problems be avoided by building it properly with the foundations and footings below the frost line?

[Matthiaswandel]

Yes. Now tell me how to go back 25 years in time and tell my dad to do that.

[Matthiaswandel]

Umm... Try watching the video again and actually listening to what I say.

Couldn't you just make the hole into a cylinder, it does not seem like that would result in frost heaving. And, it would be possible to accomplish by hand.

nice explanation, i always thought that freezing would contract the soil,  but it actually expands it and pushes the foundation up, like squeezing a watermelon seed

Matthiaswandel for Pres!

@Matthiaswandel This would be simple provided one wants to do the work. Dig out one side at a time, build a square form around the original pillar, pour new concrete with the addition of rebar added to the original pillar. A lot of work but, doable. You could even add a concrete tube large enough to fit over the existing pillar, again making sure that rebar is added to the original pillar, otherwise, just wasting time. Concrete won't stick to itself.

@Matthiaswandel oh one question, what would happen if you were to anchor the soil like some sort of upside down T shape as a foundation?
