Onsite burial involves moving knotweed contaminated soil from one part of the construction and burying it in a excavated pit lined with root barriers on another part of the site. The Environment Agency recommends that the top of the burial cell should be a minimum of 2 metres below ground level. The overall depth of the burial pit should be in excess of 5 metres deep. All root barrier seams are welded together forming an enclosed cell from which the japanese knotweed cannot escape. To prevent accidental disturbance of the burial site site, it should be recorded on all site plans and future land owners should be made aware of the location.

Choosing the location for the burial pit is important. Ideally. this should be located in areas of soft landscaping, were any ground movement such as subsidence,is limited.
