Japanese Knotweed Excavation and Removal

Japanese knotweed excavation and removal usually occurs when there is not enough time to treat it with a systemic herbicide. Under these circumstances, excavation and removal is the ideal solution. Once the site has been excavated, it can be issued with a certificate confirming the site to be clear of Japanese knotweed.

 

Japanese Knotweed Excavation and Removal – Prevention of Cross-site Contamination

Excavation and Removal Treatment by Japanese Knotweed Expert

When carrying out Excavation and Removal works on a site, Japanese Knotweed Expert take a number of steps to prevent any cross-site contamination. To do this, we will need to take the measurements of the site to ensure that the correct amount of soil is excavated.

Additional steps we take include:

  • Where possible, we designate a clean hard-standing road into and out of the site. If not possible, we use hard standing in the area where the trucks are going to be filled up with contaminated soil. We also wash the wheels of the trucks off before they leave the site. These measures are taken to prevent the Japanese knotweed from spreading.
  • We cordon off the site so that only our trained team members can access the area. This helps to further prevent any cross-contamination. Our team members are also required to clean boots and tools before moving to other areas.
  • We then remove the contaminated soil from the site. Any hard standing that has been laid where vehicles have been filled up is also removed from the site and wheels and tracks are then washed.
  • All waste is taken to a licenced landfill site. Waste carrier notes are received from the driver and the licenced landfill site. This ensures that waste is disposed of correctly and within Hazardous Waste guidelines.
  • Making the site safe is a high priority for us. We backfill the excavated area as soon as possible to prevent any accidents.

 

A large proportion of a Japanese knotweed plant is underground. We can dramatically reduce the amount of contaminated soil that is taken off-site by removing the underground stems, shoots and roots from the soil. Doing this reduces the cost of waste removal, and therefore makes the Japanese knotweed excavation and removal method as cost-effective as possible.

The best practive for the treatment of Japanese knotweed is to use a herbicide treatment. However, if you are under time constraints and would like to receive more information on how we can move your project along with Japanese knotweed excavation and removal, please contact us. We would be happy to help.
