Screening and Sifting of Excavated Soil
| Spray | Injection | Dig & Dump | Cell Burial | Root Barriers | Stockpile | Grazing | Insects | Sifting | Burning | Combined Methods |
The knotweed infested soil is dug out. It is then mechanically and manually screened to remove the rhizomes. These are taken to the landfill site and the screened soil is used elsewhere on the development. We advise that the screened soil is used in soft landscaping areas. When done properly it is a sustainable solution and very cost effective.
Soil Screening - The Myth
Contrary to what some people claim, soil screening is not a miracle, one off treatment to cure Japanese Knotweed. Let's think about this for a second, the plant can reproduce itself from an impossibly small piece of root - can you be sure that a small piece of root (rhizome) has not slipped through with the tonnes and tonnes of soil that have gone through the screening process?
The sifting and screening process is a viable technique but needs to be used in conjunction with other removal methods to combat the infestation.

Soil Screening - The Process
Our Japanese Knotweed Surveyor will arrange a site inspection and produce a Management Plan, incorporating a Method Statement, Risk assessment and schedule of works.
Typically, on larger sites, plant and machinery will need to be bought in. Our site supervisor will ensure that the Management Plan is adhered to. Soil screening will be used along side herbicidal treatment and a three year monitoring and maintenance period.
