Estudio geotécnico in Cabanas

The municipality of Cabanas is characterised by the dominant presence of sandstones, conglomerates and flysch, whereas, to a lesser extent, granitic materials, gneiss and igneous formations also occur, as well as slates and schists. The lithological composition, mostly non-clayey, favours good bearing capacity for most foundation solutions, although locally slates and schists may require verification of compressive strength and behaviour with respect to water. In addition, due to the low permeability of these materials, superficial aquifers could develop and drainage should be analysed carefully in the geotechnical study.

With regard to seismic hazard, Cabanas shows a very low level, with only two events over three decades and a maximum magnitude of 1.8, which practically rules out relevant seismic requirements in structural design calculations. There are also no risks associated with karst or the presence of expansive soils, since the bedrock does not contain predominant clays. Consequently, the main factor conditioning the geotechnical study in this municipality derives from lithological heterogeneity and the presence of local aquifers more than from significant geodynamic hazards.
