Japanese knotweed excavation and cell burial, Cornwall

Japanese Knotweed Ltd is a specialist knotweed removal contractor undertaking projects throughout Devon and Cornwall. When a private developer required the removal of knotweed for a new residential build project in Hayle, we were called in to help.

We surveyed the site and found a number of knotweed locations, one of which was located within the footprint of the proposed dwelling. A Knotweed Management Plan (KMP) was created, which included several remediation options for the client to consider.

Unfortunately, the cost of landfill disposal of knotweed in Cornwall is prohibitively high. This means that finding an on-site sustainable remedial solution is often the preferred solution for our Cornwall-based clients.

Fortunately, this particular site possessed enough space to allow for a sustainable remediation method; dig and cell burial. The knotweed was fully excavated from multiple locations and temporarily stockpiled on site. Our Site Supervisor calculated the size of the burial pit required and agreed with the client the most appropriate location for this. The receival pit was excavated and lined with specialist non-porous root barrier, after which the knotweed contaminated soil was deposited within and the root barrier returned and butyl heat-sealed over the top of the deposited material to form a secure cell. Clean spoil derived from the site was then used to backfill over the cell to a depth of 2.0m.

Our Site Supervisors are part of our fully trained and professional operations team. All works on site are completed efficiently and in accordance to the Environment Agency's ‘The Knotweed Code of Practice’, 2013. Full records of our works are retained and entered into the KMP document, which we furnish our clients with on completion.

On completion our client was able to develop the site free from the risk of knotweed. They were also afforded a 10-year Insurance Backed Guarantee.
