Estudio geotécnico in Palau-saverdera

In Palau-saverdera, the dominant subsoil is composed mainly of high-hardness overconsolidated clays and marls, which provide good bearing capacities and enable the design of shallow and direct foundations under favourable conditions of compaction and stability. Although outcrops of granite, gneiss and other igneous rocks may occasionally be found, the presence of deltaic silts and peats in localised areas advises against using these soils as a founding level, since their low strength may compromise foundation stability if they are not properly characterised or treated.

Seismic activity in this municipality is very low, with only 2 events in 30 years and a maximum magnitude of 1.7, so that seismicity represents a negligible risk factor in structural design. There are no risks associated with karstification phenomena or with the presence of expansive clays, given that the subsoil is not clayey overall. The main geotechnical constraint in Palau-saverdera will be linked to the point-like occurrence of silts and peats; detailed characterisation to distinguish and avoid these horizons will be decisive for the viability and durability of the foundations.
