Rubber Mulch 101
Rubber mulch is an affordable alternative to traditional playground surfacing materials. It is durable, cost-efficient, low-maintenance, and long-lasting. These factors make it an ideal choice for playgrounds on a budget. Below are answers to common questions to help you decide if rubber mulch fits your project.
What is rubber mulch made out of?
Rubber mulch is created from recycled tires and is commonly used in playgrounds and other outdoor kid-friendly spaces.
What are the benefits of using rubber mulch?
Rubber mulch provides more cushioning than most wood mulches, helping to reduce injury risk from falls. It typically lasts longer than wood chips and, because it is made from recycled materials, can reduce landfill waste.
What are the downsides of rubber mulch?
The biggest drawback is upfront cost compared to wood mulch or engineered wood fiber. Rubber mulch can retain heat in direct sunlight, may fade over time, and pieces can migrate outside the play area, requiring cleanup. Some buyers also raise environmental and safety questions because it is made from recycled tires.
Is rubber tire mulch safe?
Rubber mulch is widely used for impact attenuation on playgrounds when installed and maintained to applicable safety guidelines. Review local codes and current guidance before selecting a surfacing material.
Is rubber mulch toxic?
Research to date has generally found low levels of chemicals under typical use conditions, although research is ongoing. See current guidance and consider site-specific needs. For background reading, the EPA summarizes federal research on recycled tire materials.
Is rubber mulch safe for pets?
Rubber mulch is generally considered non-toxic; however, monitor pets to prevent chewing or ingestion, which can cause digestive discomfort or blockage.
How deep does mulch have to be on a playground?
Depth requirements vary by surfacing type and equipment fall height. As a general reference, the National Safety Council notes many loose-fill surfaces use about 12 inches, but follow current standards for your installation.
How many pounds is a bag of rubber mulch?
Most retail options are about 40 pounds per bag, and bulk options are available. Use proper borders so surfacing stays contained and lasts longer. Consider bulk rubber mulch, rubber curbs, or plastic timbers.
