Fondasol Hydrogéologie

Our activities

Hydrogeology Service

The water in the subsoil is a major parameter that needs to be taken on board in any infrastructure project.

Acutely aware of this major issue, FONDASOL has developed a special technical service dedicated to this problem area.

The Hydrogeology Service, based in L’Union (département of Garonne), operates across the whole of France and abroad on any issues connected with

  • water-table-structure interactions,
  • characterizing aquifers and associated water-tables,
  • storage sites for household rubbish or industrial waste (redevelopment and new sites),
  • mining sites,
  • quarries
  • water production or management.

Our hydrogeologists can get involved at all project stages: data acquisition, instrumentation, readings, interpretation and studies, project management, controls.
Fondasol’s Hydrogeology Unit offers a range of services appropriate for your projects’ requirements and issues, as part of or outside a conventional geotechnical study.

Equipped with specialist software (Visual Modflow, Surfer), this service is able to model the impact of your projects on complex aquifers.
