Estudio geotécnico in Miranda de Ebro

In Miranda de Ebro, a substrate of limestone, dolomitic and marble nature predominates, together with a significant proportion of fine sands, silts, and detrital rocks such as sandstones and conglomerates from the flysch. These materials usually provide an adequate bearing capacity for shallow foundations, and particular attention must be paid to local heterogeneity, especially in the presence of lenses of fine sands and silts. Gravel and compact sands, although less widespread, can form good load-bearing layers in those areas where they occur, while the existence of shallow aquifers should be considered in order to avoid problems associated with water on site.

Seismicity within the municipal term of Miranda de Ebro is classified as moderate, with 17 events in the last 30 years and a maximum recorded magnitude of 3.5, which does not require any special structural constraints. No relevant risks of karstification or expansivity have been identified, as the substrate is not clayey, which represents an additional advantage for the design of the foundations. The main constraint for the geotechnical viability of projects lies in lithological variability and the possible presence of water-bearing levels; these aspects must be investigated using in-situ tests and specific analyses.
