Estudio geotécnico in Palafrugell

The municipality of Palafrugell has an area dominated by compact gravels and sands, followed by a significant presence of slates, schists and, in smaller proportions, granite, gneiss and other igneous rocks. This lithological context favours moderate to high bearing capacities, suitable for most shallow foundations, with the exception of occasional levels of soft expansive clays, which require identification and, where appropriate, a load test or additional design precautions.

Seismicity in Palafrugell is very low, with only two recorded events over 30 years and a very low maximum magnitude, so it does not represent a design constraint for the structural design. The absence of karst and the predominantly non-clayey nature rule out significant risks of expansivity and associated pathologies. Thus, the main focus should be on the spot identification of layers of low geotechnical quality to ensure safe support.
