Treatment Process
Sprayer Herbicide Treatment Programme for Japanese Knotweed Control
Our Sprayer Herbicide Treatment Programme is a highly effective and professionally managed solution for controlling invasive Japanese knotweed. This method involves a series of scheduled treatment visits, where licensed herbicide applications are used to systematically weaken and suppress the plant over time.
How the Herbicide Treatment Works
Using approved knotweed herbicides, our trained technicians apply chemical treatments directly to the leaves and stems of the plant. This method:
- Targets the knotweed crown and underground rhizomes
- Exhausts the plant’s energy reserves, preventing further regrowth
- Gradually controls the infestation and halts its spread
- Reduces the risk of structural damage during the treatment period
By applying herbicides at the optimal time in the plant’s growth cycle, we ensure maximum absorption and effectiveness, achieving long-lasting control in a relatively short timeframe.
Safe and Environmentally Compliant Application
All herbicide treatments are carried out by PCA-accredited specialists holding NPTC PA1, PA6, and PA6W certifications. We strictly follow industry regulations and environmental guidelines, ensuring safe, legal, and effective knotweed control.
Japanese Knotweed Excavation, Cell Burial & On-Site Screening Services
At Japanese Knotweed Elimination Ltd, we provide comprehensive Japanese knotweed removal services, including excavation (Dig & Dump), cell burial, and on-site screening. These specialist techniques are designed for clients who need rapid, effective, and fully compliant solutions for Japanese knotweed eradication—particularly on development sites, construction projects, or where time-sensitive property sales are involved.
1. Japanese Knotweed Excavation (Dig & Dump)
Our Dig and Dump excavation method involves the full removal of Japanese knotweed, including its deep and invasive rhizome system, in a single, controlled process. Contaminated soil is carefully excavated and transported to a licensed landfill site, adhering to strict Environmental Protection Act (1990) waste disposal regulations.
This method is ideal when:
- There is limited time for long-term herbicide treatment
- Lenders, insurers, or buyers require evidence of total removal
- The site is being prepared for immediate development or construction
Once the excavation is complete, we can issue a Certificate of Clearance, confirming the site is free from Japanese knotweed.
2. Cell Burial of Japanese Knotweed
Cell burial is a cost-effective, on-site solution where excavated knotweed material is securely buried within a designated area of the property, inside a root barrier membrane that prevents regrowth or spread.
Cell burial is suitable for:
- Large sites where off-site disposal costs are high
- Projects requiring a balance between speed and budget
- Locations where contaminated material can be retained on site without disrupting future use
All burial cells are constructed to meet PCA guidelines and include long-term protection against regrowth.
3. On-Site Screening and Soil Management
On-site screening involves separating knotweed-contaminated material from clean soil using mechanical screening methods. This allows for the reuse of non-contaminated soil, reducing the volume of material sent to landfill and cutting down on disposal costs.
Benefits of on-site screening:
- Environmentally friendly and sustainable soil management
- Reduces overall project costs
- Enables faster site clearance for development
Screened material is handled in accordance with Environment Agency protocols, and we provide full documentation to demonstrate compliance.
