Natural Play in Every Way
Ages 5-12 Set kids free to explore nature and play in their own way. Made from 100% natural black locust timber, Log Jams can withstand decades of physical, imaginative, and social play. As kids shimmy up each log, the grooves and textures offer a rich sensory experience. Durable ropes and nets complement some structures, creating a haven for crawling, relaxing, and socializing.
FEATURES • Open-ended design to inspire creative, unstructured play • Activities that challenge and improve balance, coordination, and motor planning • Areas to encourage social interaction and development • Accessible entrances/exits at ground level
BENEFITS • Structures will accommodate many children at once • Black locust wood is durable, decay-resistant, and environmentally-friendly • Six-stranded steel core rope is ultra-tough but soft to the touch • Small, medium, and large structures are available to fit any space

FAQs What is the primary material used on Log Jams?
How are Log Jams installed?
Log jams are built from Robinia pseudoacacia (black locust), an eastern
Log Jams are installed with log to log connectors using galvanized
North American species. The natural, untreated wood is sourced locally
bolts, countersunk heads, washers, and nuts. Plastic spacers separate
and peeled by hand to preserve its unique curves. Robinia is ideal for
logs and eliminate the entanglement hazard. Vertical logs are set below

concern. Natural weathering may cause slight cracking, but is typical for
tapered to prevent frost heave.
natural materials and is not considered a defect. Robinia is a sustainable and environmentally-friendly material.
What is the lifespan and durability of the wood?
What is the recommended maintenance? Visually inspect each log for cracks or markings and document crack progression with photographs. Inspect logs for sharp edges and sand
The lifespan of Robinia is 25 to 40 years below grade and 60+ years above
them if needed. Inspect the sub-grade log element for rot, mold, or

fungus. Ensure there is no change in log connections, nylon spacers, and
decay, and has the highest fungi and termite resistance rating.

What type of nets and ropes are used? The ropes and nets used on Log Jams are Hercules 5/8â€? (16mm) diameter ropes with a six-strand steel core and abrasion-resistant poly sleeves. The nets are connected to the logs with a 3/8â€? SS chain and are tightened with a chain tensioner.
