The redevelopment of former landfill sites is often complicated from a regulatory, engineering and remediation perspective but Cognition’s 20 years in this field brings with it a wealth of knowledge and experience in how to navigate the various related redevelopment obstacles. Some of the issues to be addressed often include:

• Regulatory buy-in and support for the scheme
• Obtaining necessary permits, licenses and consents to allow the works to progress
• Community and stakeholder concerns and engagement
• Re-engineering the ground to provide a solid development platform
• Addressing contamination risks to controlled waters, future users and the wider environment
• Mitigating potential ground gas issues, concerns and perceptions
• Maximising reuse of materials and avoiding unsustainable disposal offsite
• Assessing and mitigating the potential for long-term settlement and contamination impacts

All of these potential risks have been addressed by Cognition Land and Water on the wide range of landfill redevelopment projects we have successfully completed over the years.

We have developed and promoted novel and innovative technologies, many of which have now become commonplace in the industry with other contractors following our lead. These include soil stabilisation using cementitious binders to improve soil properties and construct pile mats; our FabEx system for efficient removal of NAPL from groundwater; and the development of specialist, aggressive bacteria for more effective bioremediation. We develop solutions on a case-by-case basis, using our in-house talents to arrive at the most effective results for our clients.
