Estudio geotécnico in La Palma de Cervelló

In La Palma de Cervelló, local geology is dominated by the presence of overconsolidated clays and marls with high hardness. By their nature, these materials generally exhibit a high bearing capacity, although they require specific control due to the heterogeneity inherent to the marls. In addition, the low permeability characteristic of these soils promotes the development of discontinuous, shallow aquifers, which may influence foundation performance during periods of heavy rainfall. For building or infrastructure projects, it is essential to consider the compaction state of these materials in order to optimise the recommended foundation type and depth.

With regard to seismicity, La Palma de Cervelló has a very low seismic regime, with a maximum of 5 events over 30 years and a maximum recorded magnitude of 1.6, so seismic conditions do not impose particular requirements on structural design. However, the possible existence of karst-related processes should be taken into account, which could generate cavities or subsidence; it is mandatory to verify the presence of karst before any foundation is carried out. Expansive clays are present in a subordinate manner and, given local climatic conditions, pose a low or limited risk to the footings; the main constraint is the prior verification of the stability and continuity of the substratum in the event of karst phenomena.
