Playgrounds "More than 200,000 children are treated each year in U.S. hospital emergency rooms for injuries associated with playground equipment. Most injuries occur when children fall from the equipment onto the ground."(Excerpt from The Handbook for Public Playground Safety, published by the U.S. Consumer Product Safety Commission.) Playground wood chips are one of the most effective means of providing a protective surface around playground equipment, but you must maintain a 9-12" depth for maximum protection (6-9" for toddler playgrounds). Ground-FX utilizes a blower system to install playground wood chips (playground mulch) quickly and cleanly to virtually any location on your property. In most cases we are in and out in 1-2 hours, so kids don't miss their outdoor playtime. 1 yard of playground wood chips covers 324 sq ft (18'x18') to a depth of 1". Typical playground borders consist of hard railroad ties or landscape timbers. These are solid materials, more capable of causing injury. Filtrexx Safety Soxx, from Ground-FX, LLC are a soft replacement for playground surface borders. The Safety Soxx can be customized to border the exact shape and design needed for various pieces of playground equipment.
