How Deep Should My Mulch Be?

Landscaping: 1.5" - 2"

Proper mulching is critical to maintaining a healthy landscape. Not only does rubber mulch add beauty, color and texture to a landscape, it also helps control weeds, reduce water evaporation and moderate soil temperatures. It is important not to pile on too much because of the risk of suffocating and killing off your desired plants.

Residential Playground 4" - 5"

When it comes to residential playground applications, a 4” – 5” installation depth is typical based on the average height of residential playground equipment. 4” installation depth provides up to 10’ critical fall height protection and a 5” installation depth provides up to 12’ critical fall height protection

Commercial Playground 4" - 5"

According to the American Society for Testing Materials or ASTM, the standard for fall protection on commercial playgrounds is 5” – 6” depth throughout the entire play area depending on the height of the playground equipment. 5” installation depth provides up to 12’ critical fall height protection and a 6” installation depth provides up to 16’ critical fall height protection.
