Guide to the Best Playground Ground Cover Materials

best playground ground cover materials

Playgrounds are exceptionally important parts of childhood. Playgrounds are places for children to exercise, socialize and test their limits. They’re places of adventure and imagination — places of inclusion for kids of all backgrounds and abilities. Playgrounds need to be accessible and, above all, they need to be safe.

Children and adults look at playgrounds from two different perspectives. Kids see opportunities to run, play, jump and chase. They see challenges in climbing high and going fast. Adults have other views of how a playground should be. They want kids to develop muscle and coordination, but they want assurance that risks are reduced.

Playgrounds across the nation have evolved over generations. Today’s playground equipment and playground ground material are much more durable than in the past, and it’s designed with safety as a paramount concern. Gone are dangerous devices like teeter-totters and see-saws. Adventure walls, tunnels and rope meshes are popular placements. So are spiral slides and zip lines.

What’s also changed are playground ground cover options. Playground ground materials used to be limited to hard grass, gravel, sand or even concrete. These outdoor playground ground covers accounted for numerous injuries from falls and hard landings. Some falls resulted in traumatic brain injuries (TBIs), and sometimes, they were fatal.

According to the United States Consumer Product Safety Commission (CPSC), over 200,000 children are treated in emergency rooms each year across the nation. More than half of these unfortunate injuries occur from contact with hard ground. Most of these injuries are avoidable if the builders or designers first consider the best playground surface material.

Whether you’re designing a new playground or upgrading an old one, choosing the best playground ground cover is equally as important as deciding what above ground equipment you’ll use. You might just be building a backyard place for your own kids, or maybe you’re involved in a project to build a community playground. Maybe you’re a manager responsible for numerous school playgrounds or many recreational sites across a city or series of state parks.

Whatever your role in developing a children’s play facility, you need to know what to use for playground ground cover. There are many good options that provide you with the best playground ground material for playground surfaces, but it’s important to know there’s no perfect solution. What’s the right playground material for one application might not be the best for another. Ultimately, what you want and need is a safe playground ground cover.

Choosing a soft ground cover for playgrounds incorporates several key factors. Let’s look at each factor before examining what’s available and what the best ground materials are.

Factors in Choosing a Playground Ground Cover

Planning a great playground incorporates far more than just picking the right equipment. Even the best designed, most expensive and safest playground equipment won’t serve children well if the ground surface doesn’t let them enjoy comfortable tumbles and inevitable falls.

No two playgrounds are alike. Each one has their own parameters. Some are indoor, and some are outdoor. Others are on flat lots, and some work naturally hilly terrain to their advantage. They have unique situations like climate, drainage, and sun or shade patterns. They also all have varying degrees of traffic.

But what every playground has in common is that it’s built on a base or ground surface. Choosing the right ground cover relies on a total package that includes:

  • Availability
  • Maintenance
  • Accessibility
  • Appearance
  • Affordability
  • Safety

Let’s look closely at each of these six important factors for outdoor playground flooring options:

  1. Ground Cover Availability: Finding a product online or some other source might appear attractive. That’s until you discover it’s not readily available in your area and requires expensive shipping costs. It also might involve specialized installation skills or machinery. You also have to be assured your supplier is readily available in case questions or problems arise. They need to be close at hand to visit your project or lend technical support.
  2. Ground Cover Maintenance: Maintenance of playground ground cover is a huge issue, especially for commercial applications where there are limited resources for regular cleanup and ensuring the area is kept in acceptable standards. Some ground cover manufacturers advertise their products to be low-maintenance. However, it’s a buyer beware situation, and you must know you get what you pay for. Make sure your choice in ground cover takes maintenance into account.
  3. Ground Cover Accessibility: This doesn’t mean being able to access or obtain a particular type of ground cover. It refers to the Americans with Disabilities Act (ADA) that governs public playgrounds, including what types of ground covers are acceptable. This is the law, not an option, and it’s enforceable by the Department of Justice (DOJ). The ADA is very specific that ground cover materials are suitable to accommodate all people, inclusive of those with mobility and footing issues like in wheelchairs or on crutches.
  4. Ground Cover Appearance: Appearance is a definite consideration when choosing the right playground ground cover. Visit any of today’s new playgrounds, and you’ll see tremendous thought going into their overall design. That includes blending the functional equipment into the site location or terrain. A prominent sign of careful thought and planning is how they’ve chosen the right ground cover to blend the entire project together.
  5. Ground Cover Affordability: Every playground project — whether it’s your small backyard swing and slide set or a large civic maze of creative components — has budget limitations. There’s only so much money to spend, and it’s vitally important to get the best value for the money. Playground ground cover materials come in a wide range of prices. The most expensive are not necessarily the best, and this depends on the overall usage plan. But your budget should not be slashed at the expense of safety.

child safety is the most important factor when choosing the best playground surface material

  1. Ground Cover Safety: Child safety is the most important factor when choosing the best playground surface material. There are some obvious materials to avoid like concrete, stone or hard pavers, but there’s more to safety than just breaking a fall. Safety in playground ground cover materials includes health hazards like hidden foreign objects, toxic chemicals and even the attraction for pets to deposit waste. Don’t overlook safety when choosing what to use for playground ground cover. No one wants to see a child hurt, nor do they want to face a lawsuit resulting from the wrong choice in ground cover.

With these six important factors in mind, let’s now examine what materials are available for playground ground cover. This involves weighing the advantages and disadvantages of each to help you make the choice of the right materials for your playground surface.

Materials for Playground Ground Cover

There are two main types of playground ground cover. They’re categorized by the density of materials and are termed “loose materials” and “unitary materials.”

Loose Materials

Loose material means exactly what the name states. They’re granular in nature, and they are capable of being spread in various consistencies across uneven surfaces as well as being adjusted in depth. Pea gravel, sand, mulch and wood chips are examples of loose playground cover. Engineered wood fibers (EWF) are another excellent loose ground cover. Each has their own properties and are commonly found in playgrounds across America.

Loose ground covers are usually inexpensive and require minimal skill during installation. Often they’re placed by a bucket-equipped machine and then raked or shoveled into place. They do require regular maintenance — especially in high-traffic places where “kick-out” by scurrying feet under swings or at the foot of slides send granules flying.

Unitary Materials

Unitary materials are chemically bound elements that are formed into solid or semi-solid surfaces, such as tiles or rolled products like turf. Unitary materials also include solid surfaces that are poured as a liquid and are allowed to solidify as a soft, spongey surface like rubber. Artificial turf is a common unitary playground ground cover.

Unitary ground covers typically are more expensive than loose materials. Their composition is more complex and often requires experienced installation skill. They also need a better-prepared subsurface, but once they’re in place, their maintenance is lower due to high durability and strong ability to withstand kick-outs.

When choosing a loose or unitary cover for your playground, it’s important to consider some general pros and cons to each before looking at the specific advantages and disadvantages of the common ground cover types.

Pros and Cons of Loose and Unitary Ground Covers

Here are the main advantages of loose ground covers:

  • Inexpensive
  • Readily available
  • Easy to install
  • Very good impact attenuation

Some disadvantages of loose ground cover include:

  • Continuous maintenance
  • Sanitary issues from pet waste and toxins
  • Concealing hidden hazards like broken glass or sharp objects
  • Tendency to compact under wet or high traffic conditions

These are the advantages for unitary ground covers:

  • Long durability in all conditions
  • Easier to accommodate ADA requirements
  • Attractive appearance
  • Sure-footed grip for safety

Disadvantages of unitary ground covers are:

  • Higher purchase and installation cost
  • Specialized knowledge required for installation
  • May become less resilient over time
  • Availability may be an issue

You shouldn’t take each pro and con as a definite consideration. They’re more like a rule of thumb when weighing what playground ground cover is right for your application, given the important six factors. Perhaps you can adapt them to a scoring list to guide and isolate your choice.

Common Playground Ground Covers

That brings us to checking what specific materials are commonly available as playground ground covers. We’ll start with loose materials and then examine unitary ones. We’ll also make a brief mention of what ground cover materials we don’t recommend:

  1. Sand

Sand is the oldest ground cover used in playgrounds. Sand is natural, readily available, affordable and clean. It weathers well, but it has a tendency to pack hard when wet and is well known to stick onto clothing and track everywhere. Sand is no longer the popular choice for playgrounds as it’s outperformed by the new, synthetic materials.                                                     

Advantages of using sand as a ground cover include:

  • Low in cost
  • Easy to obtain and install
  • Non-flammable

Disadvantages of sand are:

  • Hard to walk on and poor for ADA compliance
  • Easy to swallow and get into eyes
  • Hides excrement and sharp objects

pea gravel is a common playground cover material

  1. Pea Gravel

Pea gravel is another old and common playground cover material. It consists of larger granules than sand, but not big enough to cause damage when cast about. The grains are the size of peas, which give it its name. Pea gravel is still popular, but it’s being replaced in many applications by synthetic materials.

Advantages of pea gravel include:

  • Economical to purchase
  • Easy to maintain and replace kick-out depressions
  • Less attractive to animals than sand

Disadvantages to pea gravel to consider:

  • Easily swallowed by young children
  • Difficult to walk through when applied thickly
  • Is not considered ADA compliant
  1. Engineered Wood Fiber (EWF)

EWF is an advanced and universally superior product to all loose materials available for today’s playgrounds. These organic fibers are manufactured from wood sources, but great care is used to ensure a pure and safe ground cover. EWF has high impact qualities to handle falls or hard impact. It’s also extremely resistant to harsh climates whether that be heat, cold, ice or rain.

EWF advantages include:

  • Excellent compaction rate for ADA approval
  • Superior fall protection
  • Very affordable surface option

Disadvantages to EWF may be:

  • Requires routine maintenance for ADA compliance
  • Capable of concealing foreign objects
  • Needs to be replenished

  1. Synthetic Turf

Synthetic turf is a popular choice for a unitary ground cover. It’s more suitable for structured applications like child care centers where a flat surface exists. Turf is also very low in maintenance and easy to spot articles that could be hazardous to children. Many colors are available when choosing turf, and it can work nicely into an eye-pleasing design.

Some advantages to using synthetic turf can be:

  • Clean and low maintenance
  • Excellent in both indoor and outdoor play areas
  • Safe from hidden objects

There are a few disadvantages to using synthetic turf:

  • Higher cost per area
  • Requires professional installation
  • Less heat resistant
  1. Synthetic Tiles

Synthetic tiles are often used for playground ground covers. They’re harder than synthetic turf but smaller and easier to handle during installation. Most synthetic tiles are a rubber-based compound, and some are composed of recycled materials like automotive tires. Synthetic tiles are popular for installing over existing surfaces like concrete slabs or asphalt lots. They require a flat and smooth substrate but give a cushion effect when in place.

Advantages to synthetic tiles are:

  • Highly durable and impact resistant
  • Excellent for renovations where a solid base is already in place
  • Highly suitable for ADA approval

Disadvantages to synthetic tiles include:

  • Expensive when compared to other ground covers
  • Requires professional installation
  • Dirt and debris can accumulate in the joint cracks
  1. Poured-In-Place Rubber

Rubber is not a common playground ground cover. Rubber ground for playground is used in projects where specialized conditions and high budgets exist. From an architectural standpoint, there are many colors available that can produce creative surface patterns. Poured in place rubber is more popular for high-end resorts and amusement parks than in civic playgrounds.

Here are the advantages of poured-in-place rubber ground cover for playgrounds:

  • Long life and durable wear
  • Very skid and abrasion resistant
  • Excellent compliance for disabled persons

There are a few disadvantages to using poured-in-place rubber:

  • Expensive playground surface
  • High skill required to install
  • Can become harder over time due to UV rays. Impact testing recommended.

Products Not Recommended

It’s worth mentioning a few products that experts don’t recommend for playground ground covers as well:

  • Grass is a hard surface and requires heavy maintenance.
  • Concrete is far too hard and very dangerous.
  • Wooden boards and decks at ground level are slippery when wet.
  • Bare earth is dirty and prone to invasive insects.
  • Loose-fill rubber can’t be made to accommodate ADA standards.

Deciding what to use for playground cover comes down to weighing the advantages and disadvantages of each cover material. It’s also necessary to consider each cover for the six factors — availability, maintenance, accessibility, appearance, affordability and safety. Overall, the clear choice is Engineered Wood Fiber (EWF).

Engineered Wood Fiber Is the Best Playground Ground Cover

Looking for the best material for your playground? More and more, playground designers and builders are turning to engineered wood fiber as their first choice for playground cover. It’s readily available, ADA compliant, economical, long-lasting, low in maintenance and above all —safe.

EWF has an attractive appearance and works well with any landscape theme. It’s slip-resistant and gives a soft, springy cushion to the ground. It also rebounds well in kick-out places. Engineered wood fiber is biodegradable and made from one of nature’s truly renewable resources.

You may think that EWF is more expensive than other ground cover alternatives, but it’s important to look at the entirety. Yes, the initial purchase cost may be slightly more than sand, pea gravel or regular wood chips, but its longevity more than makes up for the greater upfront cost. Additionally, EWF’s environmental impact is not just green-friendly to the forest. It’s healthy for the playground and especially healthy for children.
