Estudio geotécnico in Villamayor

In Villamayor, sandstone, conglomerate and flysch substrates predominate, which present favourable mechanical conditions for shallow foundations due to their good bearing capacity and stability. In areas where there are compact gravels and sands, the bearing capacity is also adequate, although its possible lateral variability should be assessed. Although slates and schists are present only occasionally, they generally provide an efficient response to support buildings, except in areas where they may present alteration or fracturing. Overall, these soils favour foundation stability and allow flexible support options, always bearing in mind the particular characteristics of each stratum.

Seismic activity in Villamayor is very low, with only 3 events over 30 years and a maximum magnitude Mmax of 2.4, which implies that seismic risk is practically negligible for structural design. Since the substrate is not clayey, the risk of expansivity is ruled out, ensuring greater reliability against volumetric ground movements. There are no indications of relevant karst phenomena. Thus, the main geotechnical constraint is the low permeability of the formations, which may influence hydrogeological behaviour and the management of groundwater for the foundations.
