What Measures Do We Put In Place?

We know that, when dealing with Japanese knotweed on a development site, there can be many other implications to the site including the risk of further contamination.

In order to make the removal of the weed as stress free as possible, and give you peace of mind, we put a number of steps in place whilst working on site:

  • Production of all relevant risk assessments and details of control measures to mitigate the risks.
  • Erection of temporary fencing to prevent any further contamination of the site.
  • Perform excavations to assess the spread of the Japanese knotweed roots.
  • Placement of signs to warn of the Japanese knotweed and avoid unauthorised access to the area.
  • Prevent any vehicular access to the area to prevent further contamination.
  • Industrial Cleaning – Including Power wash the tyres and body of any vehicle that has access to the restricted area.
  • Provide a “clerk of works” to oversee and control the treatment or removal of the Japanese knotweed.


By putting these measures in place, we can keep the risk of further contamination to a minimum and reduce the impact of the Japanese knotweed removal on your site.
