Estudio geotécnico in Getaria

In Getaria, the subsoil is mainly composed of limestones, dolomites and marbles, which account for more than 80% of the materials present, accompanied in smaller proportions by sandstones, conglomerates and flysch. This lithological assemblage generally ensures good bearing capacity for shallow foundations, although local variability and the possible occasional presence of fine sands and silts could affect stability in certain areas. It is essential to examine the continuity and possible alteration of the carbonate formations in order to define the optimal foundation type.

Seismicity in this municipality is very low, with only a single minor event recorded in the last 30 years and a very low maximum magnitude, which limits the influence of seismic action on structural projects. However, the presence of karstic ground requires a prior check for the existence of voids or cavities before carrying out any foundation, this being the main geotechnical constraint in the area and a priority in order to guarantee the safety and durability of the structures.
