Case study: Cell burial of knotweed and removal of asbestos revealed in the survey

We were contacted to discuss plans to develop a large plot affected by Japanese knotweed in Southampton, Hampshire. The site possessed large areas of Japanese knotweed, which we had been chemically treating since 2015 under a knotweed management plan for the previous landowner. We successfully completed the works to the client’s timetable. 4,500 tonnes of knotweed were buried, with an additional 8,500 tonnes of clean soils excavated for the burial pit. Total soil movements to complete the operation totalled 19,400 tonnes.
