Cement floor into existing workshop question

Around the poles, they used some type of fiber product, about a half inch thick.

Dumb question: Why is this necessary?

Would it also be a good thing with metal posts?

Thanks

Not being an engineer, as you can tell by me not even knowing what the product is called, my best guess is to provide a buffer between the post and cement floor in case of some shifting of either of the two. This would prevent cracking of the floor. I would believe that this would be a good thing to use no matter what type of post that you are using.

I will repeat that I am extremely happy with the way that the floor has stood up, considering the fill that it was placed upon and that the building is partly heated.
