Are you building or upgrading a playground in your community? Or are you responsible for maintaining a play area at your school, civic center, or some other place where kids gather to work off that endless supply of energy they seem to have?
Either way, you have probably already spent a significant amount of time researching the types of playground equipment available and gathering quotes from various suppliers. While you are at it, do not overlook the importance of the playground surfacing that will go around your new equipment! Your ability to decrease the risk and liability of serious injuries related to falls depends on the kind of safety surface material you choose.
There are several playground surface options for you to consider. They include “unitary” playground surfaces (which include uniform surfaces such as poured-in-place rubber surfacing, rubber tiles, and bonded rubber mulch) and “loose-fill” playground surfacing (like engineered wood fiber or rubber mulch).
How you choose your playground surfacing depends on the purpose of your playground, how many kids you expect to use it, the type of equipment you purchase, and your budget.
Unitary playground surfaces are smooth and uniform. They include poured-in-place rubber (“PIP”) surfacing, bonded rubber mulch, and rubber tiles. Unitary surfacing options can be more expensive than loose-fill when evaluating initial up-front costs. However, the long-term maintenance costs and costs over time may be lower.
A few key things to remember about PIP and other unitary options:
Loose-fill materials are cost-effective, traditional playground surfacing favorites because of their shock-absorbing properties (when installed and maintained at appropriate depths). They include products like engineered wood fiber and recycled shredded rubber.
A few key things to remember about loose-fill options:
A 2000 study funded by the Centers for Disease Control and Prevention demonstrated the differences between loose-fill options. The study measured the “attenuation performance” of loose-fill playground surface materials (“attenuation performance” meaning how well something can stop the impact or force of another). Among the loose-fill playground options studied, rubber mulch was the best performer. You can see information about No Fault’s loose-fill rubber mulch here.
Poured-in-place surfaces and other unitary products can be installed over asphalt, concrete, or other compacted sub-base aggregate. The thickness can be modified to comply with critical fall heights, defined as the “maximum height from which a life-threatening head injury would not be expected to occur.”
Loose-fill rubber and poured-in-place rubber are more durable than wood fibers because they won’t degrade over time. All options mentioned can give you the safety and protection you need, but the loose-fill options will require constant maintenance and testing to ensure effectiveness.
