At the end of October 2013 Japanese knotweed Ltd provided site supervision to ensure successful excavation and on-site relocation of 3,500 tonnes of Japanese knotweed contaminated material.
These works took place at a new 35 acre industrial development near Walsall, Birmingham. We originally surveyed the site and proposed a Knotweed Management Plan in 2011. The site had possessed a large Japanese knotweed problem with an extensive original infestation, plus demolished building material contaminated with knotweed. The developer was fortunate in that the site possessed enough space to allow for the excavation of the knotweed (to facilitate the development) and relocation as a stockpile in an unused area of the site. JKL orchestrated the use of 30Ton excavators, 25Ton All Terrain Dumper Trucks and a Bulldozer to complete this operation.
The relocated knotweed will be monitored and treated with herbicide, perhaps with the possibility of re-using this stockpiled spoil on site in the future, once the level of viable infestation has been reduced. The main area of the site is now free from Japanese knotweed and the developer has commenced with the build.
