Planning to build a 12 x 32 cabin on top of 6 sona tubes in the ground 2' and 2' above ground. I keep on hearing people say it has to be below freeze line in the ground so do I have to out the entire 4' of sona tube in the ground then 2' of wood above ground or would 2' in ground and 2' above ground be sufficient? In addition I will also be using pier blocks underneath the foundation for support.

Thanks Larry, we're building in southern Utah but we're right at 7000 feet. so it does drop below 0 quite often.

wow, i don't even know if i could breath at that altitude. I'm a low lander, 1000'. what is the water table like. i would assume that if you had a good snow pack as insulation the frost would not go very deep. that may be to your advantage.were you planning on a kit or stick building?

Our water table is approx 400'.....using stick building. We are planning to use brackets in the sona tubes or do you recommend putting the 4 x 4 right in the cement? I would attach pics but have not figured out how yet. Any help would be great full and I will attach.

it would be your choice on how to mount the 4x4s. using brackets would allow room for error by being able to locate the bracket where you like. as for attachments, see the "upload files" in light blue just below. click that and attach you file. it helps if you know the file name before you click on it.

I'd go with some simpson post brackets
http://www.strongtie.com/products/connectors/AB-ABA-ABE-ABU.asp
set your tubes at 3 feet, 1 foot above grade. Galv J bolt set in concrete...post bracket then is set with j bolt...this gives you some wiggle room.
you may need more than 6 for 12 x 32...that leaves 12 and 16 foot spans...
add another pier between those...
I set mine about 6 feet apart x 10 feet....and used built up beams to set I-joists

Always go 3 feet down in frost country with solid piers. Use Big Foot bottoms for great stability (& to meet building codes). There are other solutions, like rubble foundations if the digging is easy & rubble/rocks are available. Or dig over-sized shallow holes, insert hardware screen cylinder & fill cylinder with small rocks or large gravel to a foot above grade. The rock distributes the weight & drains away rain (a source of frost).
