Removal of Knotweed from Construction Sites

The Impact of Japanese Knotweed

Japanese Knotweed, an invasive species from East Asia, poses serious challenges for construction and development sites across Ireland and the UK. Its aggressive growth can damage foundations, disrupt landscaping, and compromise drainage systems, leading to costly repairs if left unmanaged. At Cork Japanese Knotweed, we provide professional identification and removal to protect your site and prevent long-term structural issues.

Why Japanese Knotweed Is a Serious Problem

The plant spreads rapidly through underground rhizomes, which can extend several metres beyond visible growth. These rhizomes can penetrate concrete, tarmac, and pipework, creating major complications for current and planned developments.

• Affected areas should be cordoned off immediately
• Removal must be carried out by qualified specialists
• Improper handling can result in legal consequences, project delays, and financial loss

Under the Environmental Protection Act 1990, Japanese Knotweed is classified as controlled waste and must be handled, transported, and disposed of following strict regulations.

Professional Management Is Essential

Unmanaged infestations can halt construction projects. Engaging Cork Japanese Knotweed ensures removal is safe, legal, and efficient, minimising disruption to timelines. We provide site-specific management plans tailored to your project and fully comply with environmental and legal requirements.

Our methods include controlled excavation, root barrier membranes, and specialised removal techniques to prevent rhizome spread and maintain clean surrounding soil.

Environmental Considerations

Japanese Knotweed outcompetes native vegetation, reducing biodiversity and destabilising ecosystems. For construction sites, unmanaged infestations can lead to legal liability, penalties, and reputational damage.

By acting responsibly, we help protect your project and the surrounding environment, maintaining site stability, value, and compliance.

Legal Compliance

Cork Japanese Knotweed ensures full adherence to:

• Environmental Protection Act 1990 (controlled waste)
• Wildlife and Countryside Act 1981
• Duty of Care regulations for waste handling and landfill

All Knotweed waste is disposed of at licensed landfill facilities to prevent contamination and ensure legal compliance.

Peace of Mind for Developers

Every removal project comes with an insurance-backed guarantee, providing financial protection against regrowth.

Partnering with Cork Japanese Knotweed ensures your site remains structurally sound, environmentally responsible, and legally compliant, allowing your project to progress with confidence.
