Floor compoundlayer location

Hi, I have the following challenge:
I want to create a list of all elements in the construction of the floor (from the concrete slab to the coating). I Get all elements with the help of a family with a vector in it.
The problem is, that some parts of the construction have compound elements. To sort them in the right order I need their location. I found this for walls but not for floors.
Has anyone an idea?
