how deep should playground mulch be 

Every year, more than 200,000 children in the U.S. are treated in an emergency room for playground-related injuries . Many of these trips to the ER could be avoided by installing protective surfacing at the right depth and thickness. The surface under and around play equipment is a crucial factor in reducing the risk of injury, especially life-threatening accidents.

Recreation surfacing such as mulch, synthetic grass and indoor carpet makes any play area safer . But the material needs to be thick and deep enough to absorb shock and provide enhanced protection against falls and tumbles.

Not sure how many inches of mulch you need for a playground? Zeager Bros., Inc. has you covered with everything you need to know about playground mulch depth requirements.

How Many Inches of Mulch Do I Need for a Playground?

The rule of thumb for how deep playground mulch should be is 8-12 inches, but every playground is different. Depth requirements for protective surfacing vary according to the materials used and the height of the equipment. Keep in mind that outdoor surfaces like grass do not provide adequate shock absorbency, and equipment should never be placed over asphalt, concrete or any other hard surface.

Playground surfacing materials are tested to evaluate their impact attenuation. Each material receives a critical fall height rating, which is the fall height below which a life-threatening injury to the head is not likely to happen. Regardless of material, your playground’s surface should be able to cushion falls from the highest piece of equipment.

Most suppliers can calculate the volume of playground mulch you’ll need based on the length and width of your playground area. To learn more about depth requirements for different materials, use our calculators as a guide.

Engineered Wood Fiber for Safe Playground Surfaces

Playground mulch depth requirements are an essential guideline for the safety of your playground, but the quality, durability and reliability of the surfacing material you use is even more important.

Engineered wood fiber (EWF) is the most popular playground surfacing due to its high-impact attenuation performance. When it’s maintained at the recommended depth of 12 inches, EWF can cushion falls from as high as 12 feet. EWF is made up of woven fibers that create a firm surface for safety and accessibility.

The stable surface of EWF meets the Americans with Disabilities Act (ADA) accessibility guidelines if properly installed. We recommend EWF to create an ADA-compliant playground surface that’s more affordable than other approved materials.
