Is this rated for ground contact please?

Thank you for your question!

The 100mm x 200mm Treated Railway Sleeper 2.4m Brown is pressure-treated for increased durability and resistance to rot and decay, making it suitable for outdoor use. This treatment helps protect the timber from moisture and fungal attack. Based on its treatment, it can be used in landscaping projects, garden edging, and raised beds. However, for prolonged ground contact, additional protective measures, such as a damp-proof membrane or wood preservative, are recommended to extend its lifespan.
