Our Jamboree Playground Tiles work perfectly for this application. Our Jamboree Tiles have a fall height rating, so if your little one were to fall, they would not be seriously hurt. Another great fact about our playground tiles is that they are made from rubber. Rubber is more slip resistant than concrete, and when wet, rubber becomes more slip-resistant making it the perfect flooring option around water. If the flooring were in direct sunlight, we would recommend going with a color other than black.
