Recycled Plastic Fencing Barriers and Roadside Bollards offer the best long term alternative to concrete or wood. Our plastic fence barriers are maintenance-free and 100% environmentally friendly. They're impervious to water, frost and insects too. Unlike composite fences and barriers, ours do not contain any wood chip, instead, our are made from 100% British waste plastic that would otherwise be destined for landfill or the ocean. See an independent WRAP study here on the longevity of recycled plastic in comparison to wood.
