Estudio geotécnico in Igüeña

In Igüeña schists and shales predominate, representing a very stable rocky substrate that provides good conditions for bearing capacity, although it may present planes of weakness that must be evaluated in detail in order to define the most suitable foundation type. The occasional presence of deltaic muds and peats indicates specific areas with soft, highly compressible soils where it is essential to avoid direct foundation support, as this could lead to unacceptable settlements.

With regard to the seismic context, seismicity is moderate, with an Mmax of 3.6, which implies that the design should include basic considerations without requiring special measures. Although the substrate is not clayey, ruling out expansivity risks, it is crucial to check for the possible existence of karst phenomena before proceeding with the foundation, since the presence of cavities or dissolution could compromise structural safety. This latest factor is the priority constraint in the geotechnical planning for the municipality.
