Make your playground as safe as possible with Rubber Mulch. It’s an attractive and superior alternative to organic mulches. It does not absorb water like wood mulch so it dries quickly after a rain and does not freeze in the winter. Unlike wood, rubber mulch does not rot, mildew, mold or decompose. The non-toxic material is naturally shock absorbent, providing a cushioned and resilient landing surface. No sharp edges means no slivers, cuts or scrapes that can result from wood chips or gravel. And it looks great too!
