INFORMATION ON PLAYGROUND SURFACING MATERIALS
The following information is from the United States Consumer Product Safety Commission's Information
Sheet for playground surfacing material. Additional Information can be found here:

Select Protective Surfacing
One of the most important things you can do to reduce the likelihood of serious head injuries is to install shock-absorbing protective surfacing
under and around your play equipment. The protective surfacing should be applied to a depth that is suitable for the equipment height in accordance with
ASTM F 1292. There are di erent types of surfacing to choose from; whichever product you select, follow these guidelines:
NOTE: Do not install home playground equipment over concrete, asphalt, or any other hard surface. A fall onto a hard surface can result in serious
injury to the equipment user. Grass and dirt are not considered protective surfacing because wear and environmental factors can reduce their shock
absorbing e ectiveness. Carpeting and thin mats are generally not adequate protective surfacing. Ground level equipment such as a sandbox,
activity wall, playhouse or other equipment that has no elevated play surface – does not need any protective surfacing.
Loose-Fill Materials:
• Maintain a minimum depth of 9 inches of loose- ll materials such as wood mulch/chips, engineered wood ber (EWF), or
shredded/recycled rubber mulch for equipment up to 8 feet high; and 9 inches of sand or pea gravel for equipment up to 5 feet high.
NOTE: An initial ll level of 12 inches will compress to about a 9-inch depth of surfacing overtime. The surfacing will also compact,
displace, and settle, and should be periodically re lled to maintain at least a 9-inch depth.
• Use a minimum of 6 inches of protective surfacing for play equipment less than 4 feet in height. If maintained properly, this should be
adequate. (At depths less than 6 inches, the protective material is too easily displaced or compacted.)
• Use containment, such as digging out around the perimeter and/or lining the perimeter with landscape edging. Don't forget to
account for water drainage.
• Check and maintain the depth of the loose- ll surfacing material. To maintain the right amount of loose- ll materials, mark the correct
level on play equipment support posts. That way you can easily see when to replenish and/or redistribute the surfacing.
• Do not install loose- ll surfacing over hard surfaces such as concrete or asphalt.
Poured-In-Place Surfaces or Pre-Manufactured Rubber Tiles
You may be interested in using surfacing other than loose- ll materials – like rubber tiles or poured-in-place surfaces.
• Installations of these surfaces generally require a professional and are not "do-it-yourself" projects.
• Review surface speci cation before purchasing this type of surfacing. Ask the installer/manufacturer for a report showing that the
product has been tested to the following safety standard: ASTM F 1292 Standard Speci cation for Impact Attenuation of Surfacing
Materials within the Use Zone of Playground Equipment. This report should show the speci c height for which the surface is intended to
protect against serious head injury. This height should be equal to or greater than the fall height – vertical distance between a designated
play surface (elevated surface for standing, sitting, or climbing) and the protective surfacing below – of your play equipment.
• Check the protective surfacing frequently for wear.
Placement:
Proper placement and maintenance of protective surfacing is essential. Be sure to:
• Extend surfacing at least 6 feet from the equipment in all directions.
