Mulch or Mats? Which is better for playgrounds?

Whether you are planning to build a playground at a home, school or park, the play surface should be of utmost concern. You'll want to keep children safe without breaking the bank. You'll also want to make sure it looks nice for a long time. Two of the most popular playground surfaces are mulch and rubber mats or tiles.

Mulch can come in many forms, including wood chips and rubber mulch, and is generally an inexpensive form of playground surfacing.

Wood chips, shredded bark mulch and engineered wood fibers are environmentally friendly, biodegradable and renewable natural resources. They'll also give your playground a natural look and feel.

Of these materials, wood chips provide the most fall height protection, ranging from 7 to 11 feet with uncompressed depths of between 6 and 12 inches, respectively. Compression does not greatly affect the fall height protection of wood chips, but does lessen the protective benefits of both shredded bark mulch and engineered wood fibers. All forms of wood mulch perform better for fall protection than hard particles of loose fill, such as sand or pea gravel.

Rubber mulch is generally made of ground up tires, extending the useful life of millions of pounds of materials that would otherwise end up in landfills. They also reduce fungus and plant growth in your playgrounds, creating a weed barriers. The elasticity of rubber mulch is excellent for shock absorption, and is far superior to wood or bark mulch in breaking falls, providing 10-12 feet of fall height protection with an uncompressed depth of 6 inches. This material will also last up to 12 times longer that wood mulch, decreasing the maintenance and replacement costs.

Unfortunately, recycled tire mulch can contain trace chemicals from the manufacturing process and use on vehicles. With that being said, the Environment Protection Agency has endorsed the use of recycled rubber for playgrounds after research determined the materials not to be harmful. Those findings have been backed by multiple other studies.

A down side to loose fill playground surfaces is that they will need a retaining barrier to be installed in order to keep the fill from spreading away from the play area. Even with a barrier, loose fill will disappear over time (in pockets, shoes and spillage over the barriers) and will need constant additions or replacements, especially in the case of wood mulches which will break down over time.

Thickness of loose fill surfaces can and will vary with use as it will be displaced from impact of children coming off slides, swinging on a swings, falling, etc. It can also be affected by wind, heavy rains or other extreme environmental conditions. Loose fill can hide potential dangers, such as screws, nails, broken glass or syringes and should not be installed over a hard surface like concrete. There is no good way to clean loose fill, especially wood mulches which attract insects and can develop mold and fungus when wet. Wood mulch can also contribute to scrapes and splinters, especially when dry.

Mats and Tiles
While more expensive to start, rubber playground mats and tiles are durable, easy to create designs or patterns and easy to maintain. They will not need any form of containment and are more handicap accessible than loose fill playground surfaces. The material will not shift or displace and any potential danger from sharp objects will be exposed on the flat surface. Mold, fungus and insects are not an issue with rubber playground flooring.

Should a rubber mat playground surface need to be cleaned, it can be easily done with a broom or garden hose. Like rubber mulch, rubber playground tiles and mats are also made of recycled tires and have been known to last for decades. Some even feature warranties of 10 years or more.

Bounce Back Rubber Playground mats from Greatmats are
fall height rated for 3-10 feet depending on their thickness.
Should a playground mat or tile become damaged, they are typically easy to replace with a new tile.

As for fall height, protection you'll want to check with each manufacturer as they can vary, depending on design and thickness. At Greatmats, you can find rubber playground tiles that are up to 4 inches thick with fall height protection of up to 10 feet.

Proper installation is critical when using rubber mats, however. Improper installation can result in tripping hazards and a decreased lifespan of your playground surface. Many rubber mats and tiles interlock, preventing seams from separating. Rubber playground tiles are also heavy, will not float or freeze, making them extremely resilient, even in extreme weather conditions.

As you can see, not all playground surfaces are created equal. When choosing your surface, make sure to consider how heavily the space will be used, the environment in which it will be installed, up front cost, maintenance, repair and replacement costs. This well help ensure children will have a fun and positive experience on your playground. By reading this, you're on the right path to protecting both your children and your pocketbook.
