Transforming brownfield sites to modern developments, safely and sustainably
Brownfield Sites

The UK was the focal point of the industrial revolution, with factories, gasworks and refineries established across almost every major town and city in the country. As technologies progressed and modernised, many of these facilities became redundant, known as brownfield sites. The result of this is hundreds of parcels of land that can potentially be repurposed for new developments. However, the soils within these sites are often contaminated with tar, chemicals and other harmful substances which pose a risk to human health and the environment.  


Over the past three decades, we have undertaken the remediation works at brownfield sites across the UK, from pharmaceutical manufacturing plants to former gasworks, laboratory testing facilities and power stations. 

Our remediation teams have successfully treated contaminated soils containing DNAPL, LNAPL, asbestos, blue billy, carbon black and various other harmful substances. 

Working with trusted testing and analysis partners, we have the capability to carry out in-situ treatment of contaminated soils, handing over the site ready for its intended use. We can also use our in-house licenced waste carrier, Erith Haulage, to transfer hazardous waste to an accredited recycling or disposal facility.

Our remediation teams have a proven track record to provide a service to the highest standards whilst complying with our client’s budgetary and programme requirements.
