Estudio geotécnico in Santa Fe

In the municipality of Santa Fe, soils of fine sands and silts predominate, accounting for more than 70% of the materials found in the subsoil. These soils usually present adequate bearing capacity for shallow foundations, although their behaviour could be conditioned by the occasional presence of gypsum, anhydrite and salts—materials that pose a risk of localised dissolution and subsidence. In addition, the limited occurrence of silts and peats in some deltaic areas implies that these strata should be avoided as a support plane for foundations, assuming a technical limitation at certain sites.

Seismicity in Santa Fe is classified as high, with 200 recorded events over 30 years, although the maximum documented magnitude remains at 4.4; therefore, while the seismic risk is significant, it does not reach extreme values. It is important to highlight that the presence of potentially karst-forming formations requires exhaustive verification before proceeding with foundations, in order to rule out possible cavities or subsidence. On the other hand, the non-clayey bedrock eliminates the risk of expansivity. In conclusion, checking for karst alongside monitoring the presence of soluble salts and the high seismic activity are the most determining geotechnical factors in the area.
