G-tec provides specialized geotechnical engineering services, as well as marine geophysical surveys and marine environmental surveys. Fields of activity are : Dredging (Rock detection & characterization, Production assessment, Geological 3D model, Environmental monitoring), Offshore Renewable Energy (Windfarm & marine turbines, Cable route and landfalls, Marine site investigation, Environmental Impact Studies), Ports & Coastal Development (Site investigation, Rock detection & characterization, UXO wrecks & obstructions, Environmental Impact Studies), Infrastructures & Civil Engineering (Waterways, High Speed Train, Tunnels, Dams), Pipelines & Cables (Detection & localization, Burial monitoring & free span, Offshore route & survey, Landfalls), Mining & Quarries (Quarries, Offshore aggregates concessions, Rock mass characterization, Overburden assessment, Exploitation monitoring & planification).

Our Mission

G-tec's mission is to offer best practice non-destructive subsurface investigation services to our clients active in Civil Engineering, Public Works, Mines and Quarries. G-tec also developed a unit focused on the management of application for concession and works licenses including but not restricted to impact assessment in marine environment.

From its academic background, G-tec wants to keep its scientific rigour and to maintain contact with a large academic community. The company had always designed and developed activities in applied sciences that are based on solid technical knowledge.

G-tec operates around the world on land and at sea with a highly qualified and motivated team of civil engineers, earth scientists, hydrographers, biologists and electronic engineers providing efficient and innovative solutions for ground investigation and hydrographic surveys.

There's no single investigation method providing a satisfying answer under all conditions. G-tec always designs its surveys and site investigation with a dedicated approach, combining if necessary the methods that are the most suited to match the scope of the project. Understanding the various methods, their possibilities and their limitations is crucial to the proper selection of techniques and to a solution oriented interpretation.

Innovation

Image

G-tec has an established tradition in developing innovative geophysical applications targeting specific issue.

Developments concern advanced software and system for data acquisition, data processing and interpretation.

In-depth knowledge of the theory behind geophysical methods, combined with extensive field experience, are the key success factor of past, present and future developments.

Some examples are the development of our Underwater Towed Seismic Refraction system, the monitoring of jet grouting operations, the acquisition and processing of magnetometric data, multisensor depth controlled tow fish operations, specific navigation software, etc.

FEATURED SERVICES

Mining & Quarries Services

In the framework of mines and quarries development projects, G-tec can provide a combination of geophysical and geotechnical techniques together with a geological site analysis in order to deliver to best 3D view of the deposits (overburden, fractures, weathering, presence of voids...). Considering that there is not always a 100% solution for getting a clear view of the expected geological situations, choosing the right combination of tools is a ...

Dredging Services

G-tec performs pre-, intermediate and post dredging surveys, to support all kind of dredging and marine construction activities (pile driving, trenching, quay walls,..) in ports, access channels and rivers. G-tec provides 3D geological model, volumes to be dredged, rock mass characterization, differential charts and cross-sections to prepare dredging and marine works. G-tec's view toward an integrated approach and its ability to deal with all the ...
