KNOTWEED REMOVAL FOR Commercial Land Owners

To ignore knotweed on land that you’ve invested in for development or to incorrectly treat knotweed can prove costly in the long term. This is why we work with you to devise the most appropriate remediation solution based on the proposals for the site. Our methods are fully compliant with legislation and codes of practice and ensure that your land can be remediated for its designated purpose.

Furthermore, knotweed needs to be disposed of in a licensed landfill by professionals with a contaminated waste removal license. Japanese Knotweed Ltd. can take care of all these problems for you with our highly trained and accredited professionals.

Whether you are at the pre-purchase stage, or have already invested in a brownfield site we can ascertain via survey whether it is contaminated with Japanese knotweed.

Contamination is a concern for remediation of these sites, but does not mean you should not consider investing. If Japanese knotweed is found we can excavate and remove it for you so your plans can proceed.

Plus we can assist you with claiming Land Remediation Tax Relief.

Japanese knotweed can be a menace for commercial property owners and businesses. If left untreated it will create thick screens of bamboo-like growth. It is highly resilient and can’t be killed with conventional means such as pulling or strimming.

Knotweed can cause damage to structures, buildings, concrete (parking areas and pathways) and underground drainage systems – as it grows it will creep through any crack or gap in the ground. It can also pose a health-and-safety risk by blocking off access routes or creating uneven hard surface areas.

Under a management plan herbicide treatments will keep the knotweed in check and force it into a dormant state, or we can quote to have it completely removed from site.

As knotweed is an invasive species classed as “controlled waste”, it can only be removed by licenced organisations. It must be disposed of safely at a licensed landfill site by a registered waste carrier. We do not advise you try to undertake this operation yourself.

knotweed removal costs

The average cost to remove Japanese knotweed varies, depending on the methods involved and the size of the affected areas. If it is identified and dealt with promptly, the costs of removing Japanese knotweed can be kept to a minimum. Long-term herbicide treatment is usually the most cost-effective control method providing successful chemical control of Japanese knotweed within a period of 3-7 years.

Excavation of Japanese knotweed costs more than herbicide treatment due to labour, materials, waste removal and reinstatement costs. However, it ensures complete Japanese knotweed removal allowing free use or development of the property. We provide cost-efficient excavation due to our extensive experience whilst minimising waste volumes.
