We sell both tiles and the roll out mats under our ArmorCover line. We are not a big fan of the mats for shops as they are much thinner than tiles, very difficult, if not impossible to repair if they get damaged, and hard to 'fit' if you want it wall-to-wall, plus often there is no insignificant waste as you need to buy the mats in rolls of standard widths. Mats are ok for parking/garages, but not for shop use in our opinion.
That being said there are times we do recommend them, namely when there is a conditioned space below since they are fully waterproof and the seams can be sealed and don't leak. Epoxy, tiles, etc cannot fully guarantee waterproofing, the mats can.
Tiles like our
www.supratile.com are solid PVC polymer, industrial grade, and easily replaced in the unlikely event that one gets damaged. We have had no reports of water or moisture issues under the tiles.
