Estudio geotécnico in Guitiriz

In Guitiriz, the dominant soils are formations of slate and schist, followed in smaller proportions by sandstones and conglomerates. These materials, generally of low permeability, provide good bearing capacity for shallow, direct foundations, although the localised presence of fine sands and silts may require precautions to avoid differential settlement. Igneous rocks, although less frequent, may require specific excavation techniques due to their hardness, but in general they increase the stability of the subsoil and provide a favourable environment for foundation work.

Seismicity in Guitiriz is considered very low, with low-frequency and low-magnitude records, which means its structural influence is minimal and it rarely affects the design of typical buildings. As the subsoil is free of expansive clays, the risk of ground expansiveness is ruled out, and there are also no risks associated with karst. The main factor to consider is the local heterogeneity of the detrital materials; the geotechnical study should identify the point presence of loose or low-competence soils in order to define the most stable foundation depth and prevent settlement-related problems.
