Estudio geotécnico in El Port de la Selva

In El Port de la Selva, the predominant geological substratum is formed by slates and schists—metamorphic materials that exhibit a laminated structure and very low permeability. Owing to their stiffness and limited deformability, these soils provide a foundation with a high bearing capacity, which facilitates the design of direct shallow foundations. However, the occasional presence of superficial aquifers in the fractures of these formations is possible, so controlling water during construction is an aspect to be considered.

Seismicity in this area is very low, with only two events in thirty years and a maximum magnitude of 1.6; therefore, seismic risk is not a relevant concern for structural design. In addition, there is no risk of karstification or significant expansivity, as the substratum is not clayey. The main geotechnical constraint will be linked primarily to the stiffness and morphology of these metamorphic rocks, together with the occasional control of groundwater in specific locations.
