HYDROLOGY AND HYDROGEOLOGY
“BUT Géologie” has all the expertise and technical know-how to apply the many and varied practical applications of hydrology and hydrogeology.
BUT Géologie is specialised in the study of water catchments and piezometers. It provides you with a team specialized in the development of specifications, including water well drilling projects. BUT Géologie is also specialised in the study of water catchments and piezometers. It provides you with a team specialized in the development of specifications, including water well drilling projects.
Our office oversees the drilling process in order to optimize the dimensioning of the structure and its equipment, according to the observations of the site.
Our team performs pumping tests and interprets the removal of wells, as well as other tasks:
- Calculating the perimeters of prevention zones around all types of basins (wells, drains, sources, etc.).
- Determination of perimeters by conducting tracing tests by measuring transfer rates inside aquifers.
- Determination of aquifers characteristics (type, hydrodynamic parameters: porosity, permeability, transmissivity, storage coefficient, etc.).

GEOTECHNICS
“BUT Géologie” is your partner to perform analyses before your mining exploration projects. These include a range of operations necessary to acquire knowledge for the qualitative and quantitative evaluation of a mineral deposit. We participate in road and construction projects as well.
The different approaches taken for geotechnical projects will measure or identify the following parameters:
- Lithostratiography and subsurface geomorphology.
- Subtances levels
- The carrying capacity of a soil (penetration tests, cavity research, pressure tests, etc.)
- Selection and design of the infiltration system for wastewater or treated water (dispersal drains, infiltration bed or mound)
- Karst areas Identification
- Conception and sizing of foundation and support projects
- Geotechnical investigation checking and supervising
- Technical support on site
GEOPHYSICS PROSPECTION SOLUTIONS
“BUT Géologie” offers its customers a range of geophysical prospecting solutions.
Electrical methods
Electrical methods are mainly based on the distribution of electrical potential in the ground. Measuring the electrical resistivity of the ground provides quantitative and qualitative results.
Geological interpretation of the results makes it possible to distinguish between healthy rock masses, altered zones, water-saturated zones and natural accidents.
Seismic methods
Seismic methods are useful in the field of civil engineering and allow to reveal the thickness of easily excitable terrains or to position the roof of the compact bedrock. They also allow to highlight the deconsolidated or karstified zones within the limestone massif or evaporites.
BUT Géologyie carries out studies of the impact of mine blasts on towns or other nearby sites in order to establish appropriate technical and safety measures.
Ground penetrating radar
Ground Penetrating Radar is a non-destructive geophysical prospecting technique based on the analysis of propagation phenomena (refraction, reflection and diffraction) of high-frequency electromagnetic waves.
The use of frequency-based georadar is a recent technique associated with instrumental constraints which has been the subject of a significant amount of research in various fields of application: Archaeology, Hydrogeology, Strategic Studies, Civil Engineering, etc.
