Estudio geotécnico in Fiñana

In the municipality of Fiñana, the predominant geological substratum is formed mainly by slates and schists, which make up more than 85% of the soils, accompanied occasionally by compact gravels and sands. These materials generally provide a good bearing capacity, although their low permeability can influence hydrological behaviour and increase water retention at the surface. The choice of foundation type will be favoured by the cohesion and strength of the slates and schists, generally allowing the use of shallow strip footings, whereas areas with compact sands and gravels may offer a suitable alternative for supporting loads from light buildings.

The seismicity in Fiñana can be considered moderate, with 11 events over the last 30 years and a maximum recorded magnitude of 2.4, which does not represent a significant threat to building construction, although it is always advisable to assess it in structural projects. The non-clayey substratum rules out risks associated with ground expansivity, so this does not constitute a conditioning factor for foundations in the area. Thus, the most relevant geotechnical aspects will be linked primarily to the soil’s density and composition, rather than to seismic phenomena or expansion-related problems.
