Commercial Knotweed Removal Methods
We tailor each remediation plan to the site’s construction schedule, ground conditions and planning requirements. Typical commercial solutions include:
• FAST System herbicide treatment for long‑term suppression
• Controlled excavation of contaminated soils
• On‑site relocation to designated receiving zones
• Dig & dump removal where immediate clearance is essential
• Soil screening, stockpiling and rhizome separation
• On‑site burial and encapsulation options
• Long‑term monitoring and reporting
• Insurance‑Backed Guarantees for lenders and warranty providers
