I have this concrete apron built with slabs along one wall of my detached garage. Is it ok to remove it, or doea it serve a purpose.

It doesn't slope away from the garage (at least not noticeably), so don't think it keeps any water away from the wall.
I dug around the edge and it is around 2-3 inches thick and it's not attached to the brickwork, so doesn't seem structural?
