Estudio geotécnico in Somozas, As

In the municipality of As Somozas, granite, gneiss and other igneous rocks predominate as the substrate, although their direct presence at the surface is infrequent (2.15%). These materials, with high competence and very low deformability, provide excellent bearing capacity, allowing shallow foundations in most cases. The low permeability of these geological formations limits the presence of significant groundwater, which favours the stability of the foundations and reduces the risk of differential settlement.

Seismic activity in this municipality can be considered moderate, with a record of 20 events in the last 30 years and a maximum magnitude (Mmax) of 1.8, placing seismic risk at low levels and with no relevant impact on typical structural design. As the substrate is non-clayey, the possibility of problems due to expansivity is ruled out. Therefore, the main geotechnical consideration for As Somozas lies in correctly characterising the local rock mass and precisely defining the embedment depth, with limited influence from other conditioning factors.
