Estudio geotécnico in Pobra do Caramiñal, A

In A Pobra do Caramiñal, the dominant substrate is made up of sandstones, conglomerates and flysch, materials that exhibit a structure characterised by good mechanical strength and stability. These types of soils provide excellent bearing capacity, favouring the feasibility of conventional shallow foundations in most projects, with minimal precautions associated with differential settlements or ground heterogeneities, generally.

Seismic activity in the municipality is at moderate levels, with 20 events over the last 30 years and a maximum magnitude of 1.8; these values do not imply relevant restrictions in the design of the foundations or in the overall planning of the works. As no presence of karst or risks associated with expansivity is recorded, the main geotechnical aspect will be the appropriate identification of the flysch levels and the characterisation of their possible internal variability—an essential element for a correct geotechnical study in the area.
