Estudio geotécnico in Maracena

In Maracena, fine sands and silts predominate; they make up the majority of the near-surface subsoil and typically behave as variable bearing-capacity soils, depending on their density and degree of compaction. White or soft expansive clays are also present in a significant proportion, but the predominance of non-clayey subsoil minimises their direct influence on the choice of foundation. In general, these conditions require detailed compaction studies and may limit the direct transmission of loads; superficial foundation solutions are therefore recommended or, if lower-resistance strata are identified, excavation should be taken down to stable layers.

The seismic hazard in Maracena is moderate, with 11 events over the last thirty years and a low maximum recorded magnitude (Mmax 2), so the seismic influence on structural design is secondary. There are no records of karst processes in the area, and the risk of expansivity is ruled out thanks to the predominance of non-clayey subsoils. Thus, the main conditioning factor for the geotechnical study in Maracena will be the correct identification and characterisation of the sandy and silty soils, paying particular attention to their compactness and associated groundwater levels.
