Estudio geotécnico in Sádaba

In Sádaba, the subsoil is composed mainly of sandstones, conglomerates and flysch, with also the presence of gravels, compact sands, as well as fine sands and silts in significant proportions. These materials usually exhibit good mechanical behaviour, which favours an adequate bearing capacity for shallow and deep foundations. However, attention must be paid to the possible heterogeneity of the geotechnical profiles, since local transitions between grain-size levels may require foundation solutions tailored to the specific ground conditions.

With regard to seismic hazard, the municipality records notable seismicity, with 68 events in the last 30 years and a maximum magnitude of 4.8, which implies the need to incorporate seismic parameters into the structural design of new buildings. There is no risk of volumetric expansion associated with the substrate as the materials are non-clayey, and there are also no signs of karstification. The main conditioning factor for the geotechnical study in Sádaba will therefore be the consideration of the local seismic response in combination with a detailed characterisation of the stratigraphy in order to guarantee the safety and stability of the foundations.
