The texture of playground surface areas is an element to question. Sand and wooden chips have a coarse texture to their surface areas that can scrape a kid's skin quickly. In fact, lots of small scrapes and injuries are triggered by the playground's surface. Wooden chips are notorious for their splinters. One incorrect move and a child will experience 10s of splinters lodged into their skin. Sandy surface areas when damp become tough and coarse. All in all, loose-filled surfaces offer a possible where children can hurt one another. Rubber mats, on the other hand, provide a smooth surface that lasts a great while.
