We developed the Eraginate® Japanese Knotweed treatment process as an alternative to the popular Dig & Dump and Stem Injection techniques. Eraginate® is not only quick but cost-efficient as well.
The treatment process involves:
- Cutting down the Japanese Knotweed plant material
- Excavating the root network within the soil matrix
- Screening of material and handpicking of roots for disposal at a suitably licensed facility
- Retention of picked material and monitoring for any signs of re-growth
- Further picking and screening if required
Once treatments are completed, the remaining soils can be re-used on-site as backfill material or in gardens and landscaped areas, subject to a minimum of 400mm clean cap cover.
Current Japanese Knotweed treatment methods include Dig & Dump, Dig & Bury and Stem Injection. These treatments are effective, yet they each have their disadvantages:
Dig & Dump: Expensive landfill disposal costs.
Dig & Bury: Restricted use available on land with the JKW still being on site.
Stem Injection: Treatments can take three or more years.
Our Eraginate® process takes all of these disadvantages away. We designed this treatment to minimise the amount of soil sent to landfill, and so reduce costs. The process also reduces the amount of time it takes to fully eradicate a Japanese Knotweed infestation, with most treatments taking just weeks to complete. Finally, all of the JKW is removed from the site, meaning there is no chance of re-growth.
Our Eraginate® treatment has proven to be effective on any size of Japanese Knotweed infestation. It shines the most on time-sensitive sites where development is pending, or a deadline is looming. And as we developed this process in-house, our team are fully skilled in delivering the results required.
