ROOT BARRIER FREE
The trench face and backfill material must be free of sharp stones and debris to ensure that there is no possibility of the barrier being punctured. The Root Barrier must be finished at least 10mm above the final surface level to mitigate the potential for root overgrowth and allowance must be made for potential drag-down of the barrier during backfilling in deeper trenches.The raised edge can be embedded in concrete or butted against a curb for longer-term protection. The Root Barrier must be installed vertically and taut against the trench side nearest the tree. Triple coated and thermally bonded twin reinforced layers.Effective against Japanese Knotweed Weed, Hog Weed and other invasive weeds.Can be installed Vertically and Horizontally.Root Barrier C3 has a life expectancy of over 50 years which is a recommended requirement by the Environment Agency with Japanese Knotweed rhizome remaining dormant for at least 20 years. It can be used vertically to prevent the lateral spread of rhizome or horizontally to protect buildings and paved tarmac surfaces.
Japanese Knotwood – used extensively for containment cells to protect clean soil, structures, hard surfaces and services from the spread of Japanese Knotweed.Service Channels – encasing new service trenches with Root Barrier C3 to protect pipes from root fracture and to provide a physical warning during any subsequent excavations.Foundations – installing a buried perimeter sheet wall of Root Barrier to prevent roots undermining foundations and control subsidence from ground shrinkage caused by trees drawing moisture out of the soil.Tree Pits – lining the sides of planting pits with C3 Root Barrier to control the spread of roots into the surrounding area where they can cause damage to property, pavements and services.
