Estudio geotécnico in Pedro Muñoz

In Pedro Muñoz, substrates of phyllites and schists predominate alongside limestones, dolomites and marbles, forming a geological setting characterised by low near-surface permeability but with potential groundwater presence at depth. The bearing capacity in these types of soil is usually favourable for shallow foundations, especially on carbonate and metamorphic formations. In limited areas with sandstones, conglomerates and compacted gravels, good support levels for foundations may also be found, although the appearance of gypsum, anhydrite and salts, albeit rare, introduces the need to assess dissolution risks that could compromise long-term stability.

The area shows notable seismicity, with 66 events recorded over the last 30 years and a maximum magnitude of 3.5, placing it within a band where seismic actions do not usually drastically condition structural design, but they should not be ruled out in detailed geotechnical studies. Given the significant presence of carbonate materials, the occurrence of karstification must be verified before defining any foundation system, as the possible presence of underground cavities is the main geotechnical conditioning factor in the municipality. The risk of expansivity can be ruled out because the substrate is non-clayey.
