We were contacted by the Martin Property Group to provide recommendations for Japanese Knotweed treatment on one of their development sites. Construction couldn’t begin until the Japanese Knotweed was removed, so a time critical solution was required.

The Challenge

The site is located on a steep slope and on multiple levels making it a challenge to work on. The majority of the Japanese Knotweed had spread along the perimeter of the site. Some of the Japanese Knotweed was growing close to the foundations of a neighbouring building meaning excavation was not possible.

The Solution

Our answer was to use our Eraginate® treatment process on the Japanese Knotweed found on level ground, this allowed us to rapidly remove the majority of the infestation. We were unable to excavate on the steep incline near to the neighbouring property, so we treated these soils with a chemical solution and installed a root barrier membrane.

We scraped all of the above ground vegetation and removed it from the site, we then treated the soil with a chemical solution. Afterwards, we placed a root barrier membrane over the soil which will prevent any re-growth in the future. Finally, we brought in clean soils to place over the membrane and released the site back, ready for redevelopment.
