Estudio geotécnico in Serinyà

In Serinyà, the predominant ground is mainly composed of white, soft clays with an expansive character, followed by occasional occurrences of sandstones, conglomerates, flysch, and deposits of compact gravels and sands. This heterogeneity in the subsoil indicates that the bearing capacity may vary significantly, making it necessary to assess the performance of the expansive clays, as they can influence the choice of foundation type to be used. The formations have low near-surface permeability, although there is potential to encounter aquifers at greater depths, which should also be taken into account in the geotechnical study.

Seismicity in the municipality is very low, with only two relevant events in the last thirty years and a low maximum magnitude of 2.5, which does not represent a special requirement for structural design. As the substrate is non-clayey in the main bearing zones, the risk of significant expansivity in the foundation is ruled out. Therefore, the primary conditioning factor for future buildings will be the accurate location of the expansive clay zones, which may require different approaches compared with the rest of the ground.
