At TERRADON, we tailor our approach to the specific project, and collect the necessary data for decision making. It’s not just about supplying the data though – we provide an understanding and a plan for our client to move forward. It’s not just collection and analyzation, it’s about educating our clients on the risks and benefits of our data and recommendations.

With the difficult soil and groundwater conditions found across the Ohio Valley and the Appalachian regions, having an experienced staff that knows the territory is incredibly important. The team at TERRADON aren’t just experts in geotechnical engineering, they are geographical experts – many of them are West Virginia born-and-raised, and understand the land where our clients build.

This has allowed TERRADON to tackle a vast variety of projects and industries, providing geotechnical investigation and advisement for everything from mining, to cell and high mast towers, to flexible or rigid pavement design. Even tasks such as landfill permitting and environmental remediation are well within our realm of experience.
