I would use it for my next driveway/slab. I would NOT use it for a tower
base. Not only is it a waste of money, it is not appropriate for a tower
base since the specs for a tower base do not call for it. IOW, you are
treading on uncharted territory if you use it there. Why take a chance?

Subject: Re: [TowerTalk] Concrete Fiber
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.
