Estudio geotécnico in Constantina

In Constantina, the dominant soils correspond to slates and schists with a very frequent presence, accompanied by occasional bands of limestones, dolomites, marbles and, to a lesser extent, granite, gneiss and sandstones. In general, these lithologies exhibit low permeability, although they may host shallow aquifers in areas of alteration or fracturing. The bearing capacity is usually suitable for shallow foundations, especially over areas of slates and schists that are little weathered. Nevertheless, the occasional presence of carbonate materials requires additional verification of heterogeneities that may influence the mechanical response of the foundation.

Seismic activity in Constantina is moderate, with 12 recorded events in the last 30 years and a historical maximum magnitude of 4.1; these parameters should be assessed in structural design, although without exceptional requirements. It is important to highlight the presence of karstic ground in certain areas due to the limestones and dolomites; for this reason, it is recommended to verify the existence of cavities or dissolution phenomena before defining the foundation solution. Finally, the non-clayey substratum rules out the possibility of problems due to expansivity, placing the verification of karstic phenomena as the main geotechnical conditioning factor in the municipality.
