Yes, but the only tile that we recommend using outdoors is Ribtrax because of expansion purposes. The solid tiles can expand at a very high rate when exposed to sun which can cause buckling. The understructure and profile of the Ribtrax allows the tile to expand and contract within itself MUCH more than a solid tile or the Sportrax. Even though the expansion is reduced immensely with the Ribtrax, slight buckling may still occur if heavy items are left on the floor in an outdoors setting (vehicles, planter pots, etc.)
