Rubber Mulch - Advantages

Advantages

Rubber mulch provides several advantages over plant material based mulches. For landscaping and gardening purposes, both nuggets and buffings insulate soil from heat, allowing a 2 or 3 degrees F higher soil temperature difference over wood mulches. Rubber mulch is beneficial for soil moisture, as rubber is non-porous and does not absorb water on its way through to the soil. It also reduces fungus growth and plant growth, and becomes a weed barrier, as weed seeds dehydrate in the mulch before reaching the soil. Neither nuggets nor buffings provide any humus to compacted soil types.

Another advantage over plant-material mulches is its elasticity, which gives it a springy quality when used in a fairly thick layer. This makes it a natural choice for playgrounds, where the extra springiness provides additional safety for children when they fall off of playground equipment. Tests have shown that rubber mulch is superior in breaking falls to traditional bark mulches. The International Play Equipment Manufacturers Association has certified some rubber mulches for ASTM F1292-09. It can be 97% wire free for landscape use and 99.9% wire free for playgrounds. Rubber mulch is also becoming a product of choice used in horse arenas for footing material when mixed with sand. It can be found in nugget or shredded style.

Rubber mulch is seen as an effective and safe alternative to wood mulch, reducing the regional and global carbon footprint by reusing materials that would otherwise end up in landfills. Its durability can be up to twelve times greater than wood mulch — with wood mulch lasting an average of four seasons — as it does not deteriorate over time.
