Estudio geotécnico in Tíjola

In Tíjola, the ground is dominated by slates and schists, materials of low permeability and competent behaviour, which form the fundamental geotechnical basis for foundation studies. Fine sands and silts are less common, but may occur locally, reducing bearing capacity if they have low density. Limestones, dolomites and marbles, although infrequent, may show localised fracturing or dissolution, whereas the presence of water masses is minor. In general, the subsoil favours shallow foundations, although in the event of small interlayers that are less competent, adjustments are required.

Seismicity is moderate, with 27 events over 30 years and a maximum magnitude of 3.6, which requires a corresponding structural review, although it does not represent an extreme constraint. Given the presence of calcareous sectors, the possible existence of karst must be checked by means of a specific geotechnical study before starting foundation works in order to rule out the presence of voids or dissolution features. The subsoil is not clayey, so there is no need to be concerned about clay expansivity. The main consideration lies in the rigorous verification of the specific risk of karstification, particularly for buildings founded on calcareous soils.
