Estudio geotécnico in Salvaleón

In Salvaleón, soils formed by sandstones, conglomerates and flysch predominate; these materials constitute the geological basis in most of the municipality. The underlying strata include, in smaller proportions, granite, gneiss and igneous rocks, as well as slates, schists and, more occasionally, limestones and dolomites. These characteristics generally imply an adequate bearing capacity for conventional buildings, although particular stability analyses are necessary if areas that are locally altered or fractured are encountered. The low permeability of these formations limits infiltration, so possible accumulations of surface water that could affect the choice of foundation system should be assessed.

Seismicity in the municipality is very low, with only one event in the last 30 years and a maximum recorded magnitude of 2, which minimises the impact of this factor on structural projects. However, there is localised karstification associated with limestones and dolomites; although it is rare, it is essential to verify the presence of cavities or dissolution before defining the foundation in order to avoid stability problems. The absence of expansive clays eliminates the risk of expansivity, with the main constraint being the identification of karstic areas in phases prior to the definitive geotechnical design.
