Contaminated land remediation with site validation


Clayton Triangle, Clayton-le-Moors


Watson Homes commissioned The LK Group to carry out remediation and site enabling on their six-acre brownfield site in Clayton-Le-Moors. The site was vacant with a mixture of remnant hardstanding and vegetation. The new development will comprise 127 homes in total, including 53 apartments and 74 houses, featuring a mix of one, two, three and four bedrooms.


We attended the site in advance of the proposed earthworks to undertake various enabling works. These included Japanese knotweed disposal, asbestos clearance, demolition of existing structures, setting up the compound area, and removal of hardstanding to facilitate archaeological investigation and further ground investigation. As part of our contaminated land remediation services, we also addressed soil contamination and prepared the site for future development.

Our team carried out a detailed site investigation, which included testing for pollutants and assessing the site’s suitability for residential development. This comprehensive approach ensured all potential hazards were identified and managed effectively.

Additionally, our remediation strategy included the use of sustainable practices, such as recycling site-generated materials for constructing piling mats. We followed the CL Code of Practice to ensure compliance and environmental safety throughout the project.


We developed a cost-effective earthworks and remediation strategy, gaining Local Authority approval through planning. Remedial works involved the removal of relic structures, including deep foundations and below-ground tanks. Contaminated land soils were remediated, and site-generated materials were utilised to construct piling mats. All works were carried out under the CL Code of Practice. Upon completion of the remediation work, we gained full regulatory sign-off for the client.

Our earthworks and piling mat designs minimised waste to landfills and maximised the sustainable reuse of materials, reducing the requirement for imported aggregates. This approach not only benefited the environment but also saved time and money for Watson Homes.
