Estudio geotécnico in Pedralba

In Pedralba, the dominant subsoil is made up mainly of slates and schists, with a significant presence of granite, gneiss and other igneous rocks. These materials, of essentially coherent and compact nature, favour an adequate bearing capacity for shallow or semi-deep foundations, reducing the need for special solutions except where altered zones are present. The very minor presence of water bodies suggests that, although there may be associated shallow aquifers, the overall impermeability of the formations limits their influence on the foundation design.

Seismicity in this area is very low, with only five events recorded over three decades and a maximum magnitude of 2.1, which implies an almost negligible seismic risk. Since the subsoil is not clayey, the problem of expansivity is ruled out, minimising risks due to swelling or shrinkage. There is no evidence of karst processes in the area, so the main factor conditioning the geotechnical study in Pedralba will be the local assessment of any potentially altered or fractured zones within the dominant rock materials.
