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.
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 ensure that vehicles and humans do not pass through the contaminated area including the root zone and that all vehicles are cleaned off before entering another part of the site.
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.
