Estudio geotécnico in Renedo de Esgueva

In Renedo de Esgueva, the predominant subsoil consists of limestones, dolomites, and marbles, often accompanied by gypsum, anhydrite and salts, in addition to layers of compacted gravels and sands. These materials generally provide an adequate bearing capacity for foundations, although the presence of gypsum and salts introduces a risk of dissolution processes that may negatively affect long-term stability. The extensive and highly permeable aquifers typical of the municipality also imply the need to analyse the influence of groundwater on the behaviour of foundations, particularly near water bodies and in areas where looser sediments may predominate.

As regards seismic risk, the area shows high seismicity, with more than 150 events over 30 years and a maximum magnitude of 4.7, which requires the inclusion of seismic parameters in the structural design of both buildings and civil engineering works. The significant presence of carbonate formations evidences a karst context, so it is essential to verify the existence of cavities or instances of dissolution before carrying out any foundation. As the subsoil is not clayey, the risk of expansivity is ruled out, and the main factors are instability associated with karst processes, risks of dissolution, and the consideration of seismicity in the structural calculations.
