Soil engineering and geosciences

_Soil: invisible and heterogeneous by nature
In all construction and development projects, the question arises of how to identify soils, which are heterogeneous by nature, hence the need to know them well.
Identifying them enables us to assess the risks and determine the best construction methods. Characterising them detects any traces of pollution that could have a lasting impact on your sites. Analysing them traces the origin of a problem or damage to a structure or building. These are the applications and issues that the Ginger Group can address to provide you with lasting solutions.

_A word from the expert
"Ginger CEBTP's Geosciences Division offers high-level identification, interpretation, and consulting services in geology, geotechnics, geophysics, seismology, geomatics, and more generally, geosciences. By integrating all these skills into 3D digital soil models, our experts characterise the natural risks originating underground that are likely to impact the integrity of an infrastructure. By analysing geological and seismic risks, our engineers study the upstream feasibility of a project and provide valuable advice to engineers on how to reduce these risks. In addition, the instrumentation of foundations and soil at sensitive sites enables the continuous measurement and detection of any geological phenomena that threaten the integrity of structures over time. The Geosciences Division is mainly involved in the public works, civil engineering, construction, industry, energy (renewable energies, oil and gas and nuclear), mining and regional planning and management sectors”
"Ginger CEBTP's geotechnical engineering offers its clients high-level consulting services for selecting the most appropriate geotechnical structures, sizing them, and monitoring their implementation. Geotechnical Engineering is based on the results of both on-site investigations and laboratory tests performed by Ginger CEBTP's own resources. The strong interaction between the men and women in the field, the laboratory and the design department enable us to control the entire value chain and produce reliable, environmentally friendly structures. Ginger CEBTP is a client-focused firm that conducts design studies for geotechnical structures and diagnostics of existing geotechnical structures, as well as monitoring of the construction of geotechnical structures in accordance with the client’s requirements. Ginger CEBTP's extensive expertise and multidisciplinary teams enable us to provide our clients with a tailored solution for all types of projects."
« For the first time in history, after decades or even centuries of unconstrained urban expansion, decision-makers are looking at how best to use the earth's land. The recent controversies surrounding Zero Net Artificialisation (ZNA) bear witness to this, and saving "land" space, which by definition has finite dimensions, is becoming a recurring issue. One of the key areas for consideration is making the most of the underground environment: for transport infrastructure, public facilities, office buildings and even homes. In addition to this universal constraint, there are much more immediate constraints: erecting a building often requires the construction of infrastructure to install equipment (boiler rooms, ventilation, generators, etc.), to store goods (shops), to park cars, etc. Underground water, which is omnipresent in France at varying depths, often complicates the task of builders. It leads to the implementation of construction measures that increase project costs, or make them unfeasible, at least at acceptable costs. Controlling groundwater, during both the construction phase and the operational phase, has become crucial: how high will the water table be in the future? How can we build without risk in an underwater environment? How can the volumes of water handled during construction be limited? What should be done during the operational phase? How can the heat from the underground environment be used? How can groundwater be replenished? In short, how can we make the best possible use of groundwater for those involved in the construction process and for the common good? For more than 75 years, Ginger BURGEAP has been supporting its clients in these areas, through its inventiveness, rigour and experience. Those of yesterday, of course, now tried and tested, but above all those of tomorrow, in the light of the impact of climate change. Thinking about groundwater - we could even say factoring it in - is one of the major challenges of the future. »

_Geotechnical engineering
The Geotechnical Engineering Division brings together in a single entity all the skills required for projects, design, project management and execution studies in the field of geotechnics, throughout France and abroad. Its added value lies in its highly technical skills, project management methods and calculation and modelling capabilities. It is organised to ensure the assiduous management of design and implementation studies. The teams work closely with all of Ginger's specialised geoscience teams, particularly in the areas of contaminated sites and soils, and hydrogeological studies. Ginger has expertise in all aspects of large-scale projects.

_Drought diagnostics
In mainland France, around half of the soil on which buildings are built is clay. Because of their water adsorption properties, clays shrink during periods of drought, which become more frequent over the years. If they are moistened during rainy spells, they can swell up, then shrink again during the following dry spell. This is known as the shrink-swell phenomenon. If this phenomenon is not properly taken into account at the design or construction stage, the soil on which the foundations of houses are laid can settle unevenly, leading to cracks and damage to facades, walls and foundations. The G5 geotechnical investigation, carried out in accordance with the NF P 94-500 standard, is a necessary preliminary step in any compensation claim, enabling the causes of the damage to be identified. Our teams carry out geotechnical investigations, then draw up a report indicating the origin of the damage. We can continue with a G2 design mission to define the repairs required to treat the structure. We work for private individuals, legal experts and numerous insurance companies.
