Playground Surface Safety

Protective playground surfacing is often the most overlooked part of home playground safety. Only about 9% of home playgrounds have a safety surface under their playsets. Most commonly, backyard playsets sit on top of grass and dirt, but neither provides adequate protection against injury due to falls.

Luckily, there are a variety of protective playground surface choices for home playgrounds that meet the need for playground safety. The cost of the surfaces range from affordable to expensive, and each choice has its own list of advantages and disadvantages. Comparing each type of surface material, you should be able to choose the playground surface that meets your home playground’s needs.

The most important piece of information to know when considering the available choices for you protective playground surface is fall height, which is the height of the uppermost part of the playset that is accessible to children. The type of playground surface you select for your home playground should be installed with a depth that is adequate for your playsets fall height.

The following is a minimum compressed loose-fill surfacing depths:

Rubber Mulch* 3” depth 7’ Fall Height
Sand 9” depth 4’ Fall Height
Pea Gravel 9” depth 5’ Fall Height
Wood Mulch 9” depth 7’ Fall Height
Wood Chips 9” depth 10’ Fall Height
There are several choices available for playground surfaces; fine sand, coarse sand, fine gravel, medium gravel, wood chips, and rubber mulch (shredded tires). In backyards, the most common materials used in our area are wood chips and rubber mulch, which are loose-fill playground surfaces.

*Rubber mulch does not compress in the same manner as the other loose-fill materials.

Let’s take a closer look at the 2 most common surfaces, the wood chips and rubber mulch.

Common Features of Loose-Fill Protective Playground Surface
