What We Did
JKSL excavated and removed from site all Japanese knotweed including soils, and then installed a 30m-long vertical root barrier along the site boundary.
The site was adjacent to a line of protected trees, so a careful and methodical excavation had to be completed. Root barriers were installed around the roots to prevent any damage to the trees.
A 5-year chemical treatment programme will allow JKSL to monitor the infestation and administer a Glyphosate based herbicide to any re-growth which occurs over the site’s 5-year chemical treatment period, as well as any growth that emerges off-site, with permission from the neighbouring land-owner.
All of the works were signed off and completed within a 1-week period, with JKSL providing an in-house warranty, and Insurance Backed Guarantee options for the plots on site.
