Estudio geotécnico in Fondón

In Fondón, slate and schist soils predominate, followed by calcareous materials such as limestones, dolomites and marbles. The substrate has low permeability, which limits the presence of deep aquifers and creates favourable conditions for shallow foundations, provided that the adequate strength and compactness of the rock ground are verified. Most of these rock materials provide good bearing capacity, although point-specific characterisation is recommended to rule out areas affected by alteration or advanced weathering.

Seismic activity in Fondón is very low, with only 8 events in 30 years and a maximum magnitude of 4, so the seismic impact on foundation design is generally low. However, special attention should be paid to the possible presence of karst in the calcareous levels, since the existence of cavities can significantly affect ground stability; it is essential to verify the absence of voids before constructing foundations. In this municipality, the main constraint for the geotechnical study is linked to the potential presence of karstification rather than seismic factors or expansivity.
