Contaminated Land

TerraConsult offers a fully integrated, multidisciplinary geotechnical and environmental contaminated land consultancy service, providing a wide range of services from initial feasibility studies and investigations through to design and project management of remediation and validation. We use the latest techniques for environmental risk assessment and risk mitigation.


Our large and experienced geo-environmental team will provide a coherent understanding of the contamination, geotechnical and regulatory issues at each site. We also take into account commercial considerations when advising on land remediation, including those relating to retention and re-use of materials, foundation design, civil engineering works and surface water drainage.
