Rubber Playground Mulch is made up of recycled rubber and works very well as ground cover under swings, slides and other play devices. It absorbs the impact of falls, what helps to reduce risk of wounds. Because of that it is commonly chosen in schools, green spaces, homes and kindergartens.
The main advantage is its long lifespan. That Rubber cover can last 10 to 20 years without breaking, getting covered by slime or attracting insects. Unlike wooden mulch, it does not break down so you do not need to commonly replace it.
Rubber Playground Mulch: Pros and Cons
Also funguses mostly avoid it. Some models are made in United States and are entirely lead-free, because they use fresh rubber instead of recycled tyres.
That material comes in various colors. One can choose between brown, blue or black, what allows creative arrangement of play areas. Some products have IPEMA certification and match with ASTM safety standards, what shows that they are tested for protection against falls.
Good makers offer even 12-year guarantee and ensure, that it is safe and almost metal-free.
Even so Rubber Playground Mulch has its downsides. The initial cost beats that of wooden version. It moves more easily, because it does not thicken, so you need to flatly set it.
Folks worry about chemicals in the rubber, and there are discussions, weather it genuinely works for children. Some cities indeed swapped rubber pavings in playgrounds with wooden mulch because of such doubts. Moreover it can get warm under sun, what matters in warm places like Tucson in Arizona.
It also can smell bad, especially after installation.
Moreover there are issues about latex allergies. Folks that are sensitive to latex maybe can not go close to playgrounds with Rubber Playground Mulch, what actually reduces the access of the area.
Wooden mulch is the main choice. It costs less, is natural and breaks down on its own. Typical kinds are pine and cedar, that give the charm of a natural look.
When play gear is removed after years, the wooden cover simply breaks down itself. Instead, rubber needs to be removed manually.
Some folks mix rubber and wooden mulch in various parts of their garden, but separating them is really hard. Landscape beams can serve as bars. Laying landscape stone below before adding Rubber Playground Mulch is a usual method for home setup.
RubberPlayground Mulch will not flush away in rain, unlike wooden, and it cleans itself while it rains.
