Can I use this outdoor?

You can use our Indoor Sports Tiles outdoors. They don't perform as well as our Outdoor Sports Tiles, but they still can be used. These tiles will drain to a certain extent as there will be some space for the water to flow through between each tile. You may get some ponding on the surface after or during a rain event. The amount of slip resistance you get will be similar to that of concrete or asphalt whether wet or dry.
