It used to be common in labs prior to epoxy. Do a search for "Pirelli floors" or something like that... that's where the Racedeck coin-pattern design came from.... My concern with any rubber floor mat type installation would be bunching up when rolling something heavy (like a loaded toolbox) across it not to mention any kind of flame/sparks. I like the ribbed style mats for parking to collect daily driver water/snow/debris, but not as a shop surface (hurts like hell when you kneel on it).
