Playground rubber mulch has a laundry list of benefits, one of them being the durability and longevity it offers. Rubber mulch will retain its safety properties for many many years and far outpaces other surfacing options. That is one of the reasons it's become so popular.
One thing that significantly contributes to the life and function of rubber mulch is the geo-textile fabric layer. Geofabric is installed on top of the ground separating the rubber mulch from the soil below. Geofabric is an often overlooked part of the installation process but offers several key benefits that help keep rubber mulch at its peak performance:
The best type of geofabric to use on a rubber mulch installation is a thick non-woven fabric. This is the same type that Rubberecycle stocks and has available to order. It feels similar to felt and allows water to permeate through it easily. It basically acts like a filter, keeping the soil out but allowing water through.
To install it, just roll out the fabric and secure it tightly against the border and all of the play structure posts. It secures to the ground easily with landscape staples. Depending on the size of the playground you'll likely have many seams where the strips of fabric come together. Make sure those seams overlap by at least 3 inches. This will ensure it stays down firmly and doesn't let anything through.
