Rubber Railroad Ties for Playground Borders: Safety & Sourcing

Rubber railroad ties make excellent, non-toxic borders for play areas—they're durable, splinter-free, and contain mulch effectively. Install them by trenching 3–4 inches deep so they sit flush and stable. Critically, ensure you're buying rubber, not creosote-treated wood ties, which are hazardous near children.

For sourcing in southeast Michigan, check agricultural suppliers like Prairie Creek Farm Services in Chesaning, which handles bulk landscape materials including rubber ties. Local landscape yards and recycled rubber distributors may also carry them. Always verify material composition before purchase.

Alternatives include composite landscape timbers, stone blocks, or poured concrete curbing—all safer than treated wood. Whichever you choose, secure the border firmly and maintain adequate mulch depth (8–12 inches) for fall protection under equipment.
