Our Vision

To transform how we understand the ground

Our Mission

To become a national centre for geo-scientific excellence and innovation, advancing the commercial applications of GeoData.

Utilising our expertise, bleeding-edge technology and big data, it is our ambition to unlock the value and unravel the complexities of the ground, enabling a safer, sustainable and more resilient society.

Our Story

Terrafirma was founded in 2015 with a clear ambition, to use our academic background to translate the scientific principles, complex processes and dynamic factors that control ground movement into opinion, advice and intelligent solutions that could enable smarter decision-making and transform ground risk assessment.

We have grown into a company unafraid to challenge the status quo, confident in our ability to positively disrupt and influence regulation, decision-making and business. It is how we became the first commercial company to be licensed to produce an official CON29M report, it is how we became the UKs leading provider of ground risk reports and it is how we continue to push the boundaries of what is commercially possible with geo-science and GeoData.

Our future is one where our innovative and intelligent solutions are at the core of simple, day-to-day decision making. Buying a house, developing land, investing money, planning our towns and cities; all will be influenced by Terrafirma and a better understanding of the ground.
