Cell Burial as a method for Japanese knotweed removal

The method involves the physical excavation and stockpiling of infested soils. A burial pit is then created, typically 5 metres deep.

The burial pit is then lined with a proprietary root barrier on the bottom and sides, with all joints welded together. The stockpile is backfilled into the burial pit. A root barrier is then laid over the surface of the infested soils and welded to the sides to form a complete containment cell.

Finally the material from the clean stockpile is laid over the containment cell with a minimum of 2 metres cover. The remaining clean material is used to backfill the previously infested area.

Alternative Japanese knotweed removal methods

The success of this method relies upon the integrity of the cell membrane, which if damaged during or after installation may result in knotweed escape. The method is likely to be less expensive than disposal off site, however it does not remove the problem from site - it simply contains it, or so you hope.

We believe better alternatives exist that focus on removing Japanese knotweed, rather than simply burying it. Our Xtractâ„¢ process is one such method.
