Did you get soil tests done? That seems really deep. We have
strong clay soils in New Mexico and Colorado, and I've always gone
4 ft in, and 6 ft out. Never an issue, with wind gusts that have
blown debris and broken modules. No footing trouble though. I
could see in a loose, sandy soil going deeper and wider.<br>
I've gotten much crazier on taller poles. I have a 20 ft tall pole
install, with several cubic yards of reinforced footer under it. <br>
The pole telescoped from 10" at the base to only 4" at the top.
Talk to a local sign company to see what they do. It's sounding
like you might be headed a bit far in the over kill direction.<br>

<div>I planning some AZ-225 tracker installs, and I would like to
avoid full excavation for slab/pier type and opt for the drilled
pier option. The pier is supposed to be 30-36" diameter and
9.5' deep. This would require a terex reedrill or similar rig.
If you know of a firm with that equipment in Wisconsin please
contact me off list.</div>

<div>Also, one site has a high water table, so any tips on pouring
in that environment would be welcomed.</div>

<div>Thanks</div>
