Estudio geotécnico in Carracedelo

In Carracedelo, the dominant subsoil is made up mainly of sandstones, conglomerates and flysch, accounting for 56% of the municipality, together with a notable presence of compact gravels and sands (29.6%). These materials usually provide good bearing capacity for direct foundations, although their low permeability may contribute to the occasional occurrence of shallow aquifers. It is important to take precautions if fine sand or silt levels are detected, but in general, the soils present make it possible to propose conventional foundation solutions adapted to the granular and consolidated nature of the main strata.

Seismicity in Carracedelo is very low, with only 4 events over 30 years and a maximum magnitude (Mmax) of 1.8, so the seismic risk is insignificant for structural design. However, particular attention should be paid to the possible presence of karst phenomena associated with carbonate materials, since the karst must be verified before carrying out the foundation to avoid potential problems of subsidence or instability. The non-clayey subsoil rules out the risk of expansivity, so the main technical constraint for geotechnical studies in the area will be checking for the karst phenomenon.
