Japanese Knotweed Japanese Knotweed is a highly invasive, aggressive species of plant. Particular problems associated with Japanese Knotweed are its ability to tolerate a wide range of soil conditions and its ability to regenerate from very small amounts of tissue.
Site Problems of Japanese Knotweed:
- Under the Wildlife and Countryside Act 1981, it is an offence to spread Japanese Knotweed.
- All parts of the plant are considered waste under the Hazardous Waste Regulations – therefore must be disposed at a licensed landfill and not reused in construction or landscaping
Knotweed can cause:
- Damage to paving and tarmac areas
- Reduction in land value
- Aesthetically displeasing
Site Works
In order to fully eradicate Japanese Knotweed present on site, VertaseFLI undertook the selective excavation of Knotweed contaminated soils.
The works consisted of:
- Site clearance of fly tipped materials.
- Site clearance of vegetation
- Removal and disposal off site of Japanese Knotweed contaminated soils
- Removal off site of excess inert materials
- Cut and fill re-profiling earthworks
