Single Season Herbicidal Treatment
In-situ herbicidal treatments represent the most environmentally friendly method of Japanese Knotweed eradication on the market. Treatment using herbicides takes six months during the active growing season to be effective.
Herbicidal Treatment for Environmentally Sensitive areas
Eradication methodologies can be tailored to suit the most environmentally sensitive areas found, including sites adjacent to watercourses, woodlands and those areas deemed ecologically sensitive.
Integrated On Site Treatment
This method involves the excavation and removal of Japanese Knotweed from the area of the site required for immediate development, and moved to a more convenient area of the same site.
Soil is passed through a variety of screening processes and spoil can be transported to licensed land fill, incinerated on site or taken to a biomass power station for use as fuel. The remaining soil can be reincorporated on the site, eliminating the need to import large quantities of back fill.
On Site Burial/ Integrated Cell Encapsulation
This involves the excavation of Japanese Knotweed, from an area required by the customer to be developed, with the contaminated spoil being buried elsewhere to a predetermined depth.
Reduced Excavation, Dig and Dump
Excavation and off site removal or ‘dig and dump’ is regularly used on land where there is a requirement for a quick solution. This however is more costly than other services offered; Soil Screening is the best alternative.
