In 2012, the ground investigation and engineering division was created, which main purpose is to execute the geotechnical, geological and geophysical campaigns, as well as the application of empirical and theoretical knowledge in the design of geotechnical structures.

Ground investigation

  • Exploratory borings
  • Undisturbed sampling
  • Standard penetration test (SPT)
  • Cone penetration test (Cptu)
  • Dynamic penetration superheavy (DPSH)
  • Dynamic penetration light (DPSL)
  • Pressumeter
  • Leugeon & Lefranc
  • Geophysical methods

Laboratory Test

  • Mechanics properties
  • Hidraulics properties
  • Dynamic properties


  • Shallow and deep foundation
  • Ground improvement
  • Retaining walls
  • Stability of excavations
  • Stability of slopes
  • Stability of levees
  • Stability of earth dams
  • Stability of earth embankments
