Looking to borrow/rent an auger to dig 7 holes

[sniper7]

I don't mind manual labor but I have 7 holes to dig for my deck project that need to be 36" deep. Not my kind of fun!

anyways, let me know if you have access to, know the best place to rent, or would let me borrow your auger to dig these things.

id be more than happy to pay your for your time/rental, beer, trade etc.

call before you dig folks have already come out, so I am ready to go.

also looking for the best price or alternatives on the tubes needed to pour the cement into for posts.

thanks guys

Most deck caisons only use sono tube if they're sticking out above ground. Unless your jurisdiction requires them you can do without.

Home Depot rents em cheap. If you need a dummy to run the other side of the auger I'd be more the happy to come by.

Ill stop by today and see what they rent them for. Probably next week I'll get to digging. I'll give you a shout, thanks for offering

Is it an issue with ground movement and freezing and what not? Everything I read/heard was to use these tubs

Ask yourself

How is cardboard going to prevent freezing and ground movement.

Better.. ask a structural engineer. He can tell you exactly how a rigid cylinder prevents horizontal shift (hint.. it has to do with physics -- which is like magic, but with math).

[Wulf202]

Its a deck on a house. All that physics when applied with logic would tell me the wood will rot out before the posts shift if properly built with or without the tubes.

Eventually that sono tube will break down and rot away. I've only used it to bring caisons above grade or if my hole got to big because of roots, large rocks, etc....
A lot of jurisdiction I work in require a 12" caison. If outside of permit I would do a minimum of 8" and if you can bell out the bottom it helps from heaving.

this is no longer correct, code will read something like this depending on your county

there will be a frost line measurement 12-48 inches typically dependent on elevation etc. (this measurement is below undisturbed or natural soil) if you are digging into ground that was just left over from the excavation of your home then you will need to go deeper in some instances to reach "natural soil" because the uncompacted crap from the last excavation is not strong enough to hold a serious deck. for a deck that are foot off the ground it probably wouldn't matter, but the code does not necessarily take that into account.

the posts cannot contact the ground and typically must clear the grade by no less than 6 inches (this is where your tube comes into play) the concrete will raise the post above grade

the posts must be pressure treated

the post must have a post base that meets your county or city codes

the posts in this photo are done correctly and passed inspection last year:



there may be some places you can allow the post to contact the ground, but i am unaware of any location in colorado that would allow this anymore. maybe Phoenix
