Soil engineering

Whatever your geological reconnaissance issue, INFRANEO helps you perform subsurface investigations, with or without drilling.

The goal: to determine the nature and chemical, physical and mechanical characteristics of each component using precise technical methods:

• Geotechnical boreholes
• Instrumentation drilling
• Geological prospecting
• Detection of cavities

Soil mechanics studies the theoretical behaviour of land cover formations as impacted by natural erosion or induced forces during the construction of structures.

These soils are classified according to physical parameters (particle size distribution, plasticity, porosity, humidity, consistency), which makes it possible to identify and describe them, and also anticipate how they will change over time.

INFRANEO conducts all the tests needed to identify, characterise and treat the soil or material by implementing:

• GTR identifications (French Road Earthworks Manual)
• Oedometer / shear /triaxial tests
• Water and soil chemical analyses

Geotechnics focuses on soil-structure interactions and conducts soil studies for the purpose of building structures, in particular, defining foundations and structural damage diagnostics.

Geotechnics also covers soil movement phenomena (landslides, subsidence, etc.) and deformations (soil compaction).

From the simplest to the most complex, INFRANEO supports you in your studies, in accordance with standard NF P 94-500 of November 2013.

In addition to geotechnical services, INFRANEO performs hydrogeological and environmental studies to precisely characterise groundwater tables and the quality of project environments.

From water management to analysing polluted sites and soils on building sites, our teams leave nothing to chance to guarantee the right conditions inherent to the organisation and smooth running of the project:

• Rainwater management
• Management of execution flows
• Variations and lowering of water tables
• Protection of infrastructure against groundwater
• Assessment of groundwater-related damage
• Regulatory files

INFRANEO offers technical assistance and project management to guarantee that the structures meet your needs and objectives in terms of deadlines, costs and quality. INFRANEO’s expertise and qualifications in structural technical assistance and project management make it the consulting partner of choice during decision-making, investigations, inspections and diagnostics.

Our teams offer public contractors support and advice to improve their understanding of technical documents and their specific features.

INFRANEO’s missions are certified by the OPQIBI 0103 </strong qualification, which acknowledges the skills and professional approach of engineering services companies.
