[TowerTalk] Concrete Base/Bed Rock

[WD0M <wd0m@centurytel.net>]

Fellow TTers,

Having just moved to a new home in Pagosa Springs, Colorado, I find that I 
am facing a problem of locating a tower base on/in bedrock.  I've received 
several suggestions from contractors in the area that I drill holes in the 
rock (which is at/near surface level on most of my 5 acres), put concrete 
rebar in the holes, use epoxy to cement them in place, then pour a concrete 
slab over it all.  Their theory is that this would hold the concrete pad in 
place, providing the stability/weight necessary to hold the tower in 
place.  (Gulp!)

My concerns are many, starting with the fact that I had planned on putting 
up a 72 foot crankup tower, weighing about 1200 pounds.  The value of the 
tower/antenna is going to be significant, and I do not relish the idea of a 
wind storm causing the supporting base/rock to crack, resulting in a loss.

Has anyone come across a problem of this nature that they have 
resolved?  Thoughts, comments, suggestions (laughter too) are solicited 
from this august group.....

73,
Joe
