Nature of works: Permeable Reactive Barrier (PRB) Decommissioning
Contract Value: £600k
Soilfix were contracted to carry out the decommissioning of Europe’s longest Permeable Reactive Barrier (PRB) at a former pharmaceutical manufacturing plant.
The Challenge
An 800m long PRB was installed directly adjacent to a live railway along the site boundary in 2000, prior to the cessation of site operations activities in 2013. The system was designed to treat a suite of groundwater contaminants of concern and reduce the potential for their off-site migration while site-wide remediation works were carried out.
Following confirmation that groundwater quality had improved to an acceptable standard, the PRB became redundant and required decommissioning in a safe, sustainable and cost-effective manner.
Our Solution
Soilfix designed and implemented a multi-disciplinary decommissioning scheme, including:
All works were completed on programme and to budget, with zero lost-time incidents/accidents, in spite of significant hazards including solvent contamination, confined space entry, temporary works, lifting operations and the adjacent live railway.
