Can these tiles be used outdoors for a backyard playground?

Our 3/8" Tight-Lock Tiles can be used outdoors. Since these interlocking tiles are made from rubber, they are very slip resistant and are more slip-resistant when wet. Being made from rubber, these tiles are mold and mildew resistant and are very easy to clean. The only thing you will notice is that when these tiles are used outdoors they can fade a bit in direct sunlight. Thes tiles could be used as flooring in a backyard playground. If you don't have any large playground equipment that is tall, these tiles would work. If you do have equipment that is a little larger, we would suggest going with one of our rubber playground tiles. These tiles have fall height ratings and will ensure that your child will not sustain serious injury while at play.
