I haven't had concrete fiber in a tower base but it is in my new driveway.
A tree fell on my new garage last June, meaning a roof and wall replacement
(one wall).  So the new fiber driveway had a dumpster, a storage unit, heavy
equipment and trucks on it, the sort of things that cracked and broke the
old driveway (unreinforced with anything that I know of).  No cracks in the
new driveway, it still looks as good as it did.  Based on my experience with
fiber concrete, I'd say go for it.
