Estudio geotécnico in Buenavista del Norte

In Buenavista del Norte, the predominant ground conditions are formed by a substrate of sandstones, conglomerates and flysch, which ensures good bearing capacity for most works. The significant presence of urban anthropogenic fill requires caution, since these materials show considerable variability in terms of strength and settlement, and are therefore usually not recommended as a stratum for direct foundation. In addition, isolated outcrops of granite, gneiss and other igneous rocks provide ideal support conditions and reduce ground deformability. The high permeability of the overall geological setting, with perched aquifers or aquifers located at the lithological contacts, implies the need to control groundwater during the excavation and foundation phases.

From the seismic standpoint, Buenavista del Norte has moderate seismicity, with 35 recorded events in the last 30 years and a low maximum magnitude (Mmax 2.1), so the structural risk associated with seismic movements is low and does not significantly condition the design of conventional foundations. There is no presence of karst or risks linked to the expansiveness of clays, which simplifies additional geotechnical considerations. In summary, the main aspect to take into account is the variability associated with anthropogenic fill and the control of permeability, since both factors are decisive for the feasibility and safety of the planned works.
