Title Infrastructures & Civil Engineering Description G-tec has a long experience in civil engineering and infrastructures related projects such as HST, waterways, bridges, roads, tunnels... The understanding of the geology and its influence on the design of the project is a condition for successful completion of each project step. G-tec has the knowledge to plan and supervise geotechnical campaigns, to carry out geophysical campaigns and to organize fully integrated site investigations on land and water. Considering that there is not always a 100% solution for getting a clear view of the expected geological situations, choosing the right combination of geophysical and geotechnical tools is a matter of knowledge and experience and of gathering as much background info as possible.

Title Mining & Quarries Description 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 matter of knowledge and experience and of gathering as much background info as possible.

Title Offshore Renewable Energy Description Sustainable energy development requires resource analysis and specific engineering geology and environmental investigations in order to describe the site conditions, and therefore identify and quantify the risks and feasibilities. G-tec assists the clients in managing the risks by carrying out relevant surveys and providing high quality reports with clear and concise data and interpretation.

Title Pipelines & Cables Description Locating pipes and cables is crucial for many marine and waterways projects. To this end G-tec uses various methods and equipments both magnetic and acoustic. The methods will be selected / combined depending on the type and size of the objects and whether they are located on the seabed or under it. Magnetometry surveys, for instance, allow the detection of small buried cables, which no acoustic method can do, by measuring the variation they bring about in the earth magnetic field. After interpretation of the data, G-tec's geophysicists are able to provide both the object location and an estimation of its size (or mass, for magnetic surveys) in the form of interpreted maps, side scan sonar mosaics, etc. Besides pipeline/cable localization, G-tec provides different services before, during and after laying of pipelines and cables; such as route investigation, geological risks assessment, trenching assessment, etc. PDF Click here to download PDF Category Consultancy Services Data Acquisition/Management Data Interpretation, Management & Processing Geotechnical Engineering & Consultancy Navigation & Position Fixing Seismic Survey & Acquisition
