Urban Splash Project – Manchester City Centre

The LK Group was commissioned by a national residential property developer to provide a remediation for a sensitive brownfield site in Manchester City Centre, situated adjacent to the River Irwell. The site, known as the Urban Splash Project, was a former cotton mill and works that had been demolished prior to commencement.

The site was demolished to slab level, however relic foundations were present, as were extensive basements and drains, culverts and sewer runs. The site was affected by the 2015 Boxing Day floods and as such there was a wide spread of Japanese Knotweed and Giant Hogweed emergences.

20 Weeks



With support form our in-house environmental consultants, The LK Group developed a land remediation scheme that allowed us to excavate certain areas of the site ready for treatment and disposal while not disturbing contaminated groundwater that was due to be remediated at a later date.

Our remediation division was also responsible for the wider remediation of the site.

Over 400m2 of Japanese Knotweed was relocated to a secure holding area before being disposed of, while the remaining Invasive Species was subjected to root barrier membranes and a herbicide treatment programme.


The LK Group’s remediation approach enabled the amount of arisings leaving the site to be reduced while also protecting the site from off-site contamination. This solution not only met the environmental objectives of the project but also allowed new service connections to be installed, enhancing the site’s potential for future development.

The successful remediation of the Urban Splash Project site was a significant achievement for The LK Group. Our work ensured that the site was safe for future use and helped to mitigate the potential environmental impact of the invasive species present. Our approach enabled the developer to progress the project and brought a valuable brownfield site back into use in Manchester City Centre.
