Estudio geotécnico in Palamós

In Palamós, the predominant geotechnical substrate is made up of granite, gneiss and other igneous rocks—materials that provide high bearing capacity and outstanding stability for shallow foundations. The compact gravels and sands present in secondary frequency also contribute to good load transfer, whereas slates and schists occur only occasionally. The predominance of igneous rocks limits the presence of friable soils, enabling the design of shallow foundation typologies with a low risk of appreciable deformations.

The seismicity recorded in Palamós is very low, with just 8 events over 30 years and a maximum magnitude value of 1.8, so the seismic risk in structural design is classified as low. Since the substrate is not clayey, the risk associated with expansive soils is ruled out. The impermeability of most formations suggests paying attention to any shallow aquifers; however, the main geotechnical constraint is the adequate characterisation of the dominant lithology in order to optimise the execution of the foundations.
