Economical and Flexible Root Barrier solution.

The economical, high-performance FlexiRoot UV5 and FlexiRoot UV10 go above and beyond the competition, offering versatility and durability at a fantastic price point while achieving standards which are equal, or even higher than those of traditional geomembranes that are three times as thick.

This flexible root barrier range offers high-performance membranes consisting of a woven HDPE base material, reinforced and coated with a triple layer of LDPE film. UV stabilised for 5 or 10 years, these root barriers are perfect for deflecting tree roots or containing Japanese knotweed rhizome growth but should be used in conjunction with a protective sand layer or fleece in most situations.
