Japanese Knotweed Removal

The excavation of Japanese Knotweed offers an immediate solution where other options are not practical.

Landtech (UK) Limited can devise a Japanese Knotweed removal and management program to suit any individual site. Knotweed removal via excavation is the alternative method to herbicide treatment and control, with our options taking into account your budget and timescales for development if necessary.

Japanese Knotweed Excavation and Stockpile On-site

Japanese Knotweed is excavated and placed on a proprietary root barrier.
Stockpile is subsequently treated with herbicides and must be left in place until declared free of Knotweed.
The stockpile may be removed typically after three years of treatment and a two-year verification period.

Japanese Knotweed Excavation and Burial On-site

An immediate Japanese Knotweed removal solution.
Knotweed is encapsulated in a proprietary root barrier cell if buried at a depth of 2 metres. If buried at 5 metres depth no root barrier is required.
Of the immediate solutions burying at 5 metres will normally be the most economical solution.

Japanese Knotweed Excavation and Removal to Landfill

An immediate Japanese Knotweed removal solution but by far the most expensive.
This may be the only solution where there is no suitable location for a burial pit or stockpile.
Under the Environmental Protection Act; Duty of Care Regulations 1991, cut Knotweed material and soil containing rhizomes must be disposed of as controlled waste. Furthermore, allowing the plant to spread onto neighbouring land can result in litigation for damages.

Japanese Knotweed Eradication & Disposal

Japanese Knotweed is an invasive and extremely resilient plant with an underground rhizome system that will require site excavation to provide an instant eradication solution with a guarantee. However, whether disposed of on-site in a controlled process or relocated to a licensed landfill site, there are a number of Environment Agency (EA) regulations relating to Japanese Knotweed eradication and disposal, which will require consideration.

Japanese Knotweed Site Survey

Japanese Knotweed can cause costly delays on large development sites, particularly when work is in progress. However, it is possible to relocate the Knotweed to a quarantined area of the site for treatment later, or remove it to a landfill site. Commercial clients who need a Japanese Knotweed removal program, can request a survey to establish the problem and risk, and from there be guided through the options to determine the best solution.
