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.
