world-class technologies and international reach, delivering stronger results to our clients.

The Power of Synergy

Driving Impact Globally

Geocomp is a leader in technology-driven geotechnical solutions, helping clients manage risk and optimize infrastructure performance. With four key groups—Consulting, Monitoring, Testing, and Products, Geocomp offers geostructural consulting, advanced monitoring, automated testing systems, and internationally recognized geotechnical lab services.

In 2022, Geocomp joined Sercel, a world leader in sensor, monitoring, and subsurface exploration technologies. Sercel itself is part of Viridien, a global technology and Earth-data group.

This partnership has enabled Geocomp to combine its deep geotechnical testing, consulting, and monitoring expertise with Sercel’s product and sensing innovations as well as Viridien’s international reach and data science / remote sensing capabilities.

The result: our clients benefit from faster insights, higher precision, and access to advanced monitoring tools.
