You can install our 8mm Designer Series Rubber Tiles - Coffee Creek outdoors. These tiles are very durable and are able to withstand the elements. Since these interlocking tiles are made from rubber, they are very slip resistant and are more slip-resistant when wet. They are very easy to clean and maintain and are resistant to mold and mildew growth. The only thing that you will notice with these rubber tiles is that in direct sunlight, they will fade over time.
