Is anyone familar with the use of helical piles for underpinning existing footings in northern climates with clay sole conditions?

Driftwood

I'm a G.C. in the Bay area. Also, a cert. welder, x pile Buck. 47 Years in the trade. They,re used a lot in clay. Chance is one Co. My friend gets his Fabbed in Canada. 4" heavy wall pipe,their Galvanizing is much heavier, than here in the states,and cheaper. There is a foot pedal and Hydraulic Guage next to it. When You reach so many kips,You're getting good refusal. You epoxy bolt Your
lifting iron and screw up to level again. I am paying $1.00 for mild steel ,just bought a ton of channel Iron. Helicals have to be spendy now.I raised one whole side of our slab home 5 years ago Two Struct. Engineers I,work with said I couldn.t do a slab on grade,I did , They're believers now! We've used them a lot. Much cheaper than re-bar piers. No dirt displaced. Go to_______

There is someone on the forums that does Helicals in North Jersey. Try and do a search he has a couple threads about them.

Where are you located? I have done some helical work it all depends on the soil conditions. Do you have boreings? What are you trying to do? How much load?

Got busy, what can I say!
Going against the odds and doing it for yourself differs the reponsiblity onto yourself. It is always nice to have a qualified stamp on it when putting someone elses house at risk.

My own home project, and others we do , are all drawn up by struct. Eng.
Permited and inspected. I'm also a cert. welder.
I know You don't have these skills. Hire a pro Like Me in Your area. Good luck

Are you making your own piers? And no I am not a welder other then doing minor repair to our equiptment. Your thought is that I would need to have a welder on staff for this type of pier. Everything I have looked at is pre-drilled and bolted.
what did you use to put the pier into ground, was it hand held or run from a boom on a skid steer. My thought is to find something hand held that can be powered by our CAT excavator. I have a concrete saw for cutting in windows and doors on concrete foundations and would like to find something that would allow me to use a hand held in crawl spaces and when we can not get the excavator close enough to run something from a boom mounted unit. I have a secondary that runs the thumb on the bucket, when the auger is attached or the concrete saw, I just secure the thumb and bypass the hydraulics.

This is very common practice for us. It's easy to confirm and or test load bearing capacity and very quick to install. Joe Nimens

We've done quite a few, but all in Southern Cal on slab-on-grade foundation systems. We use the Chance Anchor system as it's all pre-fabricated and available out of the catalog. Piers are driven to the specified depth using either a BobCat with a power take-off outside, or a hand auger drill inside. Fabulous for re-leveling too.

They also work real well as tie-backs for retaining walls or as soil nails.

Would you be interested in a less expensive way to get helicals into the ground? As fast or faster.
