Estudio geotécnico in Navia

In the municipality of Navia, soils of slates and schists predominate; these are metamorphic materials that exhibit high cohesion and generally good bearing capacity for shallow foundations. The significant presence of masses of water and, to a lesser extent, fine sands and silts, as well as outcrops of sandstones, conglomerates and flysch, introduce some locally heterogeneous conditions, although the main support levels are usually competent and stable. These geotechnical conditions favour the execution of direct foundations, making it important to identify on a case-by-case basis the presence of granular or saturated soils that may require specific solutions.

Seismic activity in the area is considered very low, with only 5 recorded events over 30 years and a maximum magnitude of 2, which suggests seismic risk that is practically negligible from a structural point of view. The subsoil is not clayey, so the issue of expansivity associated with clay soils is ruled out. There is also no risk of karstification in the area. In conclusion, the main geotechnical constraint in Navia lies in the localised presence of masses of water and the verification of the adequacy of the bearing capacity of the slates and schists in the areas of intervention, resulting in an environment that is generally favourable for construction development.
