Since its creation in 1996, Géotec's Environment department has supported and advised all of its clients (public, private, industrial, etc.) in the management of resources and constraints related to water and soil.
The team, supervised by expert engineers close to the operations on the ground, aim for the same objective: customer satisfaction, within a quality management system framework.
Géotec environment can supports you, from simple technical services to overall project management, including support for contractors and large industries.
MISSIONS
Specialities and areas within the Environment department are divided: 5 areas of work allow to integrate technical, regulatory and normative developments to respond to field and regulatory issues.
Groupe Géotec is expanding its expertise to include PFAS and microplastics, in response to changing environmental and regulatory needs. The studies we carry out now include precise environmental characterization to help you characterize environments with respect to these new pollutants.
Contaminated soil and site
In potentially contaminated lands, Géotec provides all types of services relating to the definition and management of possible pollution issues (in all types of environments), in compliance with the national methodology and existing rules and standards (particularly within standard NF-X-31620):
- Historical studies.
- Pollution diagnostics (soil, water, gas).
- Definition of initial state (0 state)
- Characterization of a local control environment.
- Definition of concentrated pollution.
- Mapping of impacts.
- Modelling of transfers.
- Management plans.
- Admissibility of earth excavated in a landfill
- Earthworks monitoring.
- Termination of activity.
- Assistance to the Client for projects and works.
- Assessment of the population’s exposure.
- Environmental monitoring.
- Validation of management scenarios with the Work Design Plan (WDP).
Geology/Hydrogeology/Hydrology and natural hazards
In the field of water, whether superficial or underground (hydrology or hydrogeology), the Environment department works on water supply, construction, energy, ecology and complex water issues. underground hydraulics.
- Geological studies: cartography, structural analysis, geological synthesis.
- Studies of watersheds: geomorphological analysis, calculations of characteristics (velocities and coefficients of runoff, erosive factors).
- General hydrogeological studies: supply basins, installation of boreholes, protection of resources and pumping, collection of water sources.
- Hydrogeological studies to define characteristic water levels: Higher, medium lower levels Waters.
- Estimation of dewatering flows in the works and final phases.
- Design of pumping devices.
- Drilling monitoring, pumping tests, multi-tracing of underground water.
- Qualitative monitoring of water resources.
- Low temperature geothermal energy (on groundwater / dry probes).
- Numerical modelling of underground flows (VISUAL MODFLOW Flex software).
- Assistance during the works phase: catchment, development and prevention and protection works, drainage, etc.
Geothermics
Pre-feasibility studies for small-scale geothermal solutions based on groundwater resources and/or subsoil energy using vertical probes.
Géotec is OPQIBI RGE/1007 qualified (eligible for ADEME subsidies).

Human resources for the environment department
Géotec's Environment department is spread throughout mainland France, so as to be as close to the field as possible and to intervene as quickly and efficiently as possible. In total, the department is made up of a team of 30 engineers and technicians specialized by field of intervention. In addition to the daily partnership with the geotechnical teams, they also work in support of the Group's various subsidiaries, notably Géotec Afrique, Géotec Guyane and Lacq, based on Reunion Island.
