BACKGROUND
We were instructed by our client a building contractor to carry out a survey within the Kings Heath area. Japanese Knotweed was found on site whereby the contractor has been asked to demolish an existing wall and replace with new wall. Japanese Knotweed was known to be present on site with a historic treatment plan in place.
SITE SURVEY
During our site survey, it was evident that the Japanese Knotweed infested areas would most definitely be disturbed during the building works. So it was highly recommended that a Japanese Knotweed technician is to be present on site whilst the works are carried out to ensure no contamination or spread of Japanese Knotweed within the site.
A technician would attend whilst the site was set up prior to commencement of works, ensuring protective membrane is laid in the appropriate areas.
A technician would then attend site to supervise the dig out of footings. As and when Japanese Knotweed is found within the soils, this would be screened and Knotweed Services (UK) Ltd will manually screen any material that arises and place any rhizomes in dumpy bags and place the bags in the secure biosecurity area on site.
Once all the Japanese Knotweed material from all the areas has been bagged and sealed, these would then be transported to licensed landfill in Cheltenham under EPA1990 Duty of Care guidelines.
