Greg et al ..
Sounds way over done, to me .. we spend a lot of time on TT about concrete
and towers, my question to the group is who has some REAL stories about
tower failure due to concrete base errors? I don't personally know of any,
but they must exist, or there would not be all this discussion on the
subject. 73

Subject: [TowerTalk] Tower base advise
Not sure if I over did this or not. My neighbor brought his backhoe over
this afternoon to dig the foundation for my HG-70HD tower and raising
fixture.
The specs only call for a 4x4x8 hole. While we did not quite hit 8ft (a bit
over 7 in the middle), the dimensions came to 6.5 x 6.5. Thats 270 cubic ft
vice 128. Is the slightly shallower depth going to make a big difference?
I attached a couple pics.
I hope to schedule the concrete pour for this week. 4000 psi and gonna have
it poured pretty wet. Do I need to get one of those vibrating things or is
pouring it wet sufficient?
Thanks
Greg
