Surfaces

Playground mulch is engineered wood fiber (EWF) sized, shaped, and tested to absorb impact at standard fall heights under ASTM F1292. Regular landscape mulch from a garden center is shredded bark or hardwood that hasn't been tested for fall protection. Landscape mulch compacts unevenly, can hide debris, and loses loft within a season, which makes it unsafe under swing sets or climbers. If the surface is going under play equipment, use a tested playground surface material, not landscape mulch.

Playground mulch thickness depends on the equipment's fall height. CPSC guidance recommends 9 inches of compressed mulch for fall heights up to 7 feet, and 12 inches for fall heights up to 10 feet. Engineered wood fiber compacts roughly 25 percent after installation, so order extra to hit the final depth. Playground rubber mulch compacts less but should still be installed to the same protective depths. Use a depth gauge near high-traffic zones like the bottom of slides and under swings, where displacement happens fastest.

For most backyard swing sets, engineered wood fiber and rubber playground mulch are the practical favorites. EWF costs less upfront but compacts and needs annual top-offs. Rubber mulch costs more to install but holds its depth for over a decade with minimal maintenance. Pour-in-place rubber is the premium choice for commercial playground installations and yards where mobility access matters, since it creates a smooth ADA-friendly surface. Pea gravel works at low fall heights but tends to scatter and isn't accessible.

A geotextile fabric goes under playground mulch. It acts as a weed barrier, allows water to drain through, and stops the mulch from mixing into the soil below. Without it, organic matter migrates downward, the surface thins out faster than it should, and weeds work their way up through the mulch.

Our Duraliner Geotextile Fabric handles this job under engineered wood fiber, rubber mulch, or pea gravel for residential and Cincinnati playground equipment installs alike. Lay it across the prepped base before you pour any loose-fill on top.
