Tetra Tech provides robust and pragmatic geo-environmental advice to unlock the potential of development sites and identify potential risks and liabilities.

Good geo-environmental advice is essential to ensure projects proceed safely, efficiently, and sustainably. Tetra Tech’s geologists, geotechnical engineers, hydrogeologists, geochemists, and risk assessors provide robust and pragmatic technical advice that caters to client’s specific needs.

We put regulatory and commercial issues at the centre of all solutions. Our dedicated in-house ground investigation team has extensive experience across a range of sectors, including heavily controlled and regulated environments such as railways, highways, and operational energy site
