Estudio geotécnico in Fuente Obejuna

In Fuente Obejuna, a substrate made up of slates and schists predominates, accompanied by occasional outcrops of granite and gneiss, as well as by compact layers of gravels and sands. This composition determines soils with medium to high load-bearing capacity, which usually allows for shallow direct foundations, provided that the geotechnical continuity of the strata is verified. The overall low permeability, characteristic of these lithologies, helps to limit the presence of water beneath the foundations, although possible perched aquifers must be considered at specific locations.

Seismic hazard in the municipality is very low, with only nine events over three decades and a maximum magnitude of 2.9, thereby ruling out the need for special structural provisions for this reason. The absence of clayey materials in the substrate eliminates any risk of expansivity. Therefore, the most relevant technical factor for the geotechnical study will be the local assessment of the degree of weathering and continuity of the slates and schists, which will condition the homogeneity of the supporting ground.
