Hi Bob,
I had a similar issue - and resolved it with
epoxy/rock cement and drilling holes using a
hammer drill to put 25 rebar rods in place. The
difference is that my tower base is all above
ground, because I have bedrock 6 inches under the
soil on almost all of my 5 acres.
I've had my tower up for almost 3 years, and it's
withstood 88 mph wind gusts that blew out the
front windows in my home with not a single
problem. Was I nervous when I did it? Yup. I'm
very comfortable with the decision, and it's
worked very well. It's a free standing US Towers TX-455.
You can see it on my web page at:

Click on Ham Radio, then "Tower Project".
Hope that helps!
73,
Joe
