Why are pieces of stones used to cover the ground at electric switchyards instead of just having a concrete floor ?

This is the kind of very odd and specific question and answer that makes me super suspicious
It’s cheaper than concrete, requires almost no maintenance, drains well, compacts well for moving heavy gear and trucks, and there is usually a grounding grid built underneath the whole substation which requires the whole area to be dug subgrade and backfilled, for which gravel is a good material.
My first job was at the Centralia hydro project, it goes beyond gravel but that’s 16ft of gravel. Keep in mind those *wires* are 2inch by 12inch flat copper *wires*. A massive amount of juice goes thru that switch yard. A guy got melted wearing a full arc suit but lived due to his PPE. Our safety manager had one arm, burned completely off. The lineman in every state who handle storms are completely unsung heros.
