How is it that the concrete under the ice doesn’t crack with all the freeze \ thaw? Anybody know?

There's an element of truth to the magic potion. The concrete mixture is somewhat customized depending on what is being poured (support columns, walls, floors etc.) . The concrete slab itself that the ice will sit on is also massively thick compared to the other floor slabs and will be composed of very high strength concrete.
