Japanese Knotweed Excavation

Removal for Construction and Development Sites

At Cork Japanese Knotweed, we understand that complete removal of Japanese Knotweed is often essential before any construction or development can begin. Severe infestations may require excavation and remediation to ensure your site is safe, compliant, and ready for building.

Understanding the Problem

Japanese Knotweed is a highly invasive species. Its rhizomes can extend up to 7 metres from visible growth, spreading undetected underground. Infestations can compromise foundations, drainage systems, and retaining walls, making professional removal critical for any development project.

Legal and Regulatory Requirements

Strict regulations govern the removal, transport, and disposal of Japanese Knotweed and contaminated soil.

• Improper handling can result in cross-contamination, legal liability, and project delays.
• Developers must engage registered and licensed contractors; DIY removal is illegal and may lead to prosecution.

Professional Removal Solutions

1. On-Site Disposal - Excavation & Screening

Our "Zero to Landfill" approach separates contaminated rhizomes from clean soil using specialist screening. Contaminated material is:

• Transported to a licensed landfill, or
• Incinerated on-site under approved regulations

Benefits:

• Cost-effective: saves up to 65% compared to traditional dig-and-dump
• Fast, year-round application with immediate results
• Environmentally responsible with a lower carbon footprint
• Fully compliant with all regulations

2. Cell Burial & Excavation

Contaminated soil can be relocated and buried in a root-barrier-lined pit, sealed in polyethylene to allow natural decomposition underground.

• Pit depth: 5 metres or more, top at least 2 metres below ground
• Fully documented for future landowners
• Up to 70% cost savings compared to traditional landfill

3. Off-Site Removal and Disposal

Where on-site disposal isn't feasible, all excavated material is safely transported to a licensed landfill for complete eradication.

All methods comply with the Environmental Protection Act 1990 and Duty of Care guidelines, ensuring biosecurity and legal compliance.
