The following images show a case study of work carried out on a commercial site, infested with Japanese Knotweed. It was important that the knotweed management was carried out quickly and thoroughly so the development could proceed on time and within budget.
Southwest knotweed was commissioned to dig out the area for Japanese knotweed cell burial, in South Molton, North Devon. This saved the developer thousands of pounds by keeping the Japanese Knotweed on-site. The knotweed was simply moved away from the footprint of the development build.
- Digging out the area for Japanese Knotweed Cell Burial
- Next step to protect the membrane by a side liner
- Sand in the base to protect the membrane
- Lower membrane inserted
- Nearly ready to take the Japanese Knotweed
- Japanese Knotweed rhizome – excavated
- Japanese Knotweed rhizome high-lighted with spray paint and chased back, excavated ready to be moved to the cell area
- Just over 125t of contaminated soil, now in the cell
- More sand to protect the top membrane
- All wrapped up
- Top Hat – Top membrane put into place
- Last of the sand for protection. Lower and top membrane bonded together
- Clean soil / aggregate loaded back into hole, and will be filled with 2mt high, up to ground level.
