Rubber mulch does not degrade and can technically last the lifetime of the playground if maintained properly. With minimal maintenance, you can expect it to last up to 10 years. While other mulches such as engineered wood fiber mulch generally need to be replaced annually due to the rate at which it decomposes, the longevity and durability of rubber mulch is one of its biggest selling points. Whether you’re using rubber mulch for playground surfacing or for gardening, you can rest easy knowing it won’t need to be replaced annually.
That said, the ultimate lifespan of rubber mulch depends on a variety of factors, including proper installation and regular maintenance. Installing rubber mulch on a level surface is key to ensuring the safety of children on the playground, as well as the continued existence of the playground it’s placed on. One intangible that could affect the lifespan of rubber mulch is weather and other environmental elements. Though rubber mulch is anti-fade and more durable than other mulch types, the effects of weather will make themselves apparent over time. As the years go by, extreme sun exposure as well as fluctuating temperatures can contribute to the wear and tear of rubber mulch.
There are a number of ways to further increase the lifespan of rubber mulch beyond the 10-12 years it’s meant to last. First, installing a weed barrier prior to laying rubber mulch will help deter weeds from growing beneath the mulch, as well as enable most minor maintenance such as raking. Additionally, frequent removal of sticks, leaves, and other debris will help rubber mulch to stay clean and safe for use as a surfacing material for kids at play. Allowing these items to accumulate on the playground over time makes it more difficult to keep the space safe, so it’s recommended that rubber mulch on playgrounds be regularly cleaned and inspected for debris or other foreign objects that could become tripping hazards.
