Estudio geotécnico in Calahorra

In Calahorra, geotechnical studies must take into account a predominance of compact gravels and sands which, together with the frequent presence of sandstones and conglomerates, provide good bearing-capacity conditions for foundations. However, the occasional presence of gypsum, anhydrite and salts introduces the risk of dissolution processes, especially in areas where the groundwater table is high. It is essential to avoid areas of muds or peats as support and to carefully assess the continuity of the competent lithologies at the project site.

The seismicity recorded in the municipality of Calahorra is very low, with low magnitude and frequency, and it does not represent a relevant constraint for structural design. Nevertheless, the possibility of karstified developments linked to gypsum and salts requires detailed checks prior to foundation design, since the existence of cavities or dissolutions may compromise stability. The non-clayey nature of the subsoil rules out expansive risks. The main constraint identified in the area is the need to verify the existence of karst and potential voids associated with it before building the foundations.
