Estudio geotécnico in Pioz

In the municipality of Pioz, a substrate consisting mainly of limestones, dolomites and marbles predominates, representing close to 55% of the soils, followed by sandstones, conglomerates and flysch. This composition implies the existence of competent materials with good bearing capacity, which makes it possible to consider conventional foundation solutions in most cases. Nevertheless, the presence of extensive and discontinuous aquifers with moderate permeability and discharge may influence hydrogeotechnical behaviour, so it is essential to assess the stability and drainage of the ground before selecting the type of foundation.

From the seismic point of view, Pioz shows a high level of activity with 200 events over 30 years and an estimated maximum magnitude of 4.6, which requires the incorporation of seismic criteria in the structural design. Additionally, since karst is present in the area, it is essential to verify the existence of cavities or dissolutions before proceeding with the support of the structures, as they can affect the safety and functionality of the foundations. Finally, the absence of an clayey substrate rules out the risk of expansivity, so the main limiting factors focus on the potential for karst features and seismicity.
