Estudio geotécnico in Sant Vicenç dels Horts

In Sant Vicenç dels Horts, the predominant geotechnical substrate consists of high-hardness overconsolidated clays and marls, together with a significant proportion of limestones, dolomites and marbles. Fine sands and silts also occur commonly, whereas slates and schists are less frequent. These conditions generally indicate good bearing capacity, although the sandy and silty layers may show local variability, requiring detailed characterisation. The use of deep foundations or strip footings depends on the precise location and the nature of the dominant lithological horizon. In addition, the carbonate formations (limestones and dolomites) require verification of the presence of karst processes before defining the foundation solution.

Seismicity in Sant Vicenç dels Horts is very low, with only 3 recorded events over 30 years and a maximum magnitude of 3.1, so seismic regulations have a minimal impact on structural design. The non-clayey substrate eliminates the risk of expansive behaviour, which optimises the safety and durability of the foundations. However, the possible presence of karst in calcareous materials is the main geotechnical limiting factor, requiring specific geotechnical study to avoid differential settlements or localised collapses during construction.
