> I need to have a hole for my new tower 6' x 6' x 7.5' deep. Due to
limited lot size that I live in, and mainly to keep peace in the
family, I am looking at removing my old tower base 4' x 4' x 5' deep
and it contains no re-bar, just tower base stubs. I can't remember
what grade of concrete it is, but it is about 14 years old. I am
limited to 2 types of removal, crane and Armstrong method. The crane
company won't make any guarantee's they can complete the job due to
complications etc, and want a hefty payment up front. I am now
looking at having a young guy come by and use a Jackhammer to do the job.
Has anyone tried demolishing their old tower base and how long did it
take any problems etc. Since this undertaking is new to me I am open
to suggestions and or comments and hopefully some good suggestions.
Actually your existing base is pretty large. How much bigger does it
have to be for the new tower?
While the LXC Prime Directive is to "DO what the manufacturer says", you
might be able to get away with enlarging the existing hole. If the base
isn't cracked somewhere, dig out 2 sides of it, drill and epoxy in some rebar
and fill it in with concrete. Then adapt the new base to the hole. I've done
this several times with no problems.
The role of the rebar is to keep the concrete from cracking so by
adding the rebar in the expansion, the new stuff should be just fine.
It sounds like you haven't had any fatal problems with the existing
base so adding to it, despite its shortcomings would probably solve your
