Japanese Knotweed eradication

The treatment and eradication of Japanese Knotweed is a common requirement on construction and civil infrastructure projects in all areas of the country; it is said that there is not a single square kilometre in the UK that does not have Japanese knotweed growing within it. The cost to the UK economy of dealing with Japanese knotweed is estimated to in the region of £2 billion.

Three Shires uses the following techniques (or a combination of the below) to eradicate the JK:

  • Herbicide treatment including stem injection
  • Cell burial/site encapsulation
  • Soil screening
  • Managed and monitored excavation and disposal
  • Insulation of root barrier membranes

As well as providing eradication solutions our team carry out JK and Invasive weed site surveys, produce detailed Invasive weed reports as well as precautionary methods of working and Japanese Knotweed management plans.

For many of our large construction clients we are able to provide Japanese Knotweed clerk of work services; this allows customers to use their on-site plant and resources under our instruction to deliver the remediation works. This reduces cost whilst maintaining best practice and compliance with legislation.

Control of Invasive weeds

Although Japanese Knotweed is the most high profile invasive weed developers and contractors should be aware of other invasive plant species. The wildlife and countryside act 1981 schedule 9 part II gives a list of Invasive plant species that if present on development sites may require control.
