Estudio geotécnico in Espinosa de los Monteros

In Espinosa de los Monteros, the dominant materials are limestones, dolomites and marbles, followed by sandstones, conglomerates and flysch. These lithologies provide good bearing capacity for foundations, although the local presence of shallow aquifers in formations that tend to be of low permeability must be taken into account when planning earthworks. The stiffness of these soils favours the use of shallow foundations in most cases, depending on the depth of the firm stratum and the stratigraphic nature of the ground.

With regard to additional factors, seismic activity in the area is moderate (11 events recorded in 30 years, Mmax 3.3), and although it does not represent a major constraint, it should be analysed during the design stage. It is important to highlight the karst potential of the carbonate materials, which requires an exhaustive check for the presence of voids or cavities before proceeding with any type of foundation, since karst can compromise stability. The non-clayey substratum rules out the risk of expansive soils, identifying karst as the main constraint to be controlled.
