Commercial Invasive Weed Remediation and Control
Specialist invasive weed survey, treatment and remediation services for commercial sites, infrastructure projects, developers, contractors and public sector organisations.
Oliver Brown Ltd supports larger invasive weed projects, including Japanese knotweed, giant hogweed, horsetail, bamboo, contaminated soils and rhizome removal. We provide practical management plans, compliant disposal options and site-specific remediation support for projects where invasive weeds could affect the programme, increase risk or create long-term management issues.
Japanese Knotweed, Giant Hogweed and Invasive Weed Management
Invasive weeds can create serious issues on construction, infrastructure, development and land management projects. Left unmanaged, species such as Japanese knotweed, giant hogweed, horsetail and bamboo can affect site safety, programme timescales, soil movement, legal responsibilities and long-term land value.
Our role is to help clients understand the extent of the issue, choose the right treatment or removal method, and complete works in a way that is practical, compliant and suited to the wider project.
We work with commercial contractors, local authorities, developers, landowners and organisations managing larger sites where invasive weed control needs to be planned properly from the outset.
Japanese knotweed
Survey, management, treatment and removal options for commercial sites affected by Japanese knotweed.
Giant Hogweed
Specialist control and management support for sites where giant hogweed presents a safety or access risk.
On-site Cell Burial

Clear, site-specific treatment plans to support remediation, construction sequencing, planning conditions, land sale requirements or ongoing site management.
