Method Three: Cell Burial / Root Barrier

If there is enough space on-site, a cell burial or the use of a root barrier can be used to avoid the high cost of transporting infested Knotweed soil and debris to a licenced landfill.

Cell burial entails burying Japanese Knotweed to a minimum depth or, if encapsulated, burying the Japanese Knotweed material within a geo-membrane that can be closer to the surface.

Root barriers can be installed both vertically (where there is a possibility of cross-border contamination) and horizontally (when there is no risk of cross-border contamination).

If there is enough space on-site to bury or employ a root barrier system for the Knotweed, cell burial or root barrier approaches are applied. Knotweed trash is buried to a minimum depth on-site using cell burial, and if encased within a geo-membrane, it can be buried closer to the ground’s surface using geo-membrane burial.

If there is a possibility of cross-border contamination, root barrier barriers can be used and erected both vertically and horizontally. To physically control and inhibit the spread of Knotweed, root barriers are used. If there is a suitably sized area for it to be buried, this method can be employed on both building sites and residential homes.

These strategies are best used on construction sites where building and construction activities must begin rapidly.
