Geotechnical and hydrological studies

Geotechnical studies

Knowledge of the subsoil is becoming more and more important, which is the support for human activities, excavation, storage or construction materials, hence the importance of the geological-geotechnical study as a basis for civil engineering projects.

Geological-geotechnical studies aim to develop geological, geomechanical and geotechnical models that allow knowledge of the behavior of subsoil materials.

Geology provides the necessary information for lithological, structural, geometric, geomorphological, hydrogeological behavior recognition, etc.

Geotechnics provides the tool from a geomechanical point of view of identification, aggressiveness, expansivity, resistance and deformability of materials.

The compendium between the two disciplines guarantees the optimal solution of problems in civil engineering. The work methodology is made up of field studies , land surveys and laboratory tests :

  • In the field study , geological mapping work is carried out, Geotechnical: lithology, structure, hydrogeology, geomorphology and geotechnical features.
  • In the prospection of the land, the following work is carried out:
    • Superficial works: pits, wells and ditches.
    • Geophysical prospecting: seismic, electrical and radar.
    • Penetrometrics: static and dynamic.
    • Mechanical surveys: rotation, roto-percussion and helical.
  • In the laboratory, soil identification analysis and testing, analysis, testing and petrographic studies of rocks are carried out.

We manage the most modern equipment for exploration, thus guaranteeing a true zoning of the substrate that, when placed in the correct places, provides a diagnosis of the situation.

What are our geological-geotechnical studies for?

  • Civil, industrial and service works (foundations, slabs, piles, underpinning of buildings…).
  • Linear works (roads, railways, etc…).
  • Excavations and slopes.
  • Mining and quarries.
  • Detection, prevention and mitigation of geological risks (expansiveness, landslides, karstification, flooding, erodibility, etc…).
  • Geological, geomorphological, hydrogeological, geotechnical cartography, etc…
  • Geophysical surveys (geoelectric, seismic, georadar…).
  • Assessment of environmental impacts.

Hydrological studies

We carry out hydrogeological studies with geoelectric prospecting to determine the aquifer properties of the subsoil, especially to know the subsurface stratigraphic profile, defining the clay horizons, the layers of gravel and sand, the position of the water table and the basement.

We carry out the following Hydrogeological studies:

  • Hydrogeological Reconnaissance for hydrogeological mapping (1/5000 digital map with aerial photos), Inventory of water points (sampling), Surface Hydrology (hydroclimatic balances), Hydrothermalism (monitoring of gauges and springs), etc.
  • Hydraulics of the catchments for study of the Structure of the catchments and other discharge points, recharge or not of the “quaternary”.
  • Hydrochemical Characterization for carrying out first analyses, hydrochemical context, microbiology, hydrogeochemistry and medical hydrology.
  • Legal aspects for consultation on delegation of mines, requests, etc.
