PNR has undertaken extensive remediation works on land and buildings for its clients since its inception in 2001.

Typically we are instructed prior to site disposal, acquisition or redevelopment plus end-of-lease dilapidations, in order to comply with relevant legislation and Environment Agency requirements. We have remediated sites throughout the United Kingdom suffering from various degrees of contamination and involving a range of contaminants from asbestos through to hydrocarbons and chemical pollution.

Successful and economic remediation requires a comprehensive site investigation and subsequent remediation strategy relevant to the proposed use. Typically works can include specialised asbestos removal, off-site contaminated soil removal, on-site contaminated soil treatment, in situ ground water treatment, on-site containment and capping and site reinstatement.

PNR were appointed to clean up this vacated industrial site on the Finisklin Industrial Estate, Sligo, Ireland which had been contaminated both internally and externally by extensive oil spillage.

This was a redundant wood preservative manufacturing unit which had been extensively contaminated with chrome, cadmium, arsenic and hydrocarbons together with extensive asbestos in the main structures. The client requested that it be remediated prior to sale. PNR successfully remediated and it sold with no contamination retention or liability.


PNR undertook a comprehensive, Environment Agency-approved risk analysis of the site and the works were phased as follows:

Asbestos strip of all structures prior to demolition of all existing buildings and slab breakout.
Sealing of all redundant internal drainage works and removal of all underground storage tanks.
Identification and removal of hot spot contamination.
In situ ground water remediation followed by membrane lining to prevent recontamination.
Installation of new substation civils.
