[RE-wrenches] Wattsun Tracker Foundations

[Solarguy]

We've installed a number of AZ225s and big Zomeworks trackers to date. There
are a number of companies that do foundation pier drilling but only a
handful that have the capacity for a 36" pier. Even fewer will drill thru
rock if it's down there. 

Water must be pumped out when it starts to collect and dealing with that
pita is something to take up in advance with the cement contractor.

Hey Wrenches,

 

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.

 

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

 

Thanks
