Estudio geotécnico in Villayón

In Villayón, the predominant subsoil is composed of slates and schists, representing more than 80% of the ground. These materials, generally of low permeability, provide a rock foundation with good bearing capacity for shallow foundations, although their presence can lead to local variations in ground strength, requiring attention in the specific geotechnical characterisation of the construction site point. The low permeability favours direct foundations and limits risks associated with dissolution processes or compressible soils, while the presence of masses of water is occasional and is usually linked to small, near-surface aquifers.

Seismic activity in the area is very low, with only three events over thirty years and a very low maximum magnitude, so it does not constitute a relevant constraint for the structural design of buildings. Likewise, the analysis of expansivity rules out associated risks, since the subsoil is not clayey and no expansive soils are detected. In summary, the main geotechnical constraint in Villayón is determined by the compact, low-deformability nature of the schists and slates, which provide a reliable base for buildings except in very specific cases.
