Geotechnical study in Nueva Carteya

In Nueva Carteya, soils formed by limestones, dolomites and marbles predominate; these are high-competence materials with high bearing capacity, which favours the use of shallow foundations for most buildings. However, the frequency of shallow aquifers and the occasional presence of sands, conglomerates and silts require a detailed analysis of the hydrogeological setting and the precise location of the groundwater levels. Hard clays and marls are uncommon and, given their limited representativeness, they scarcely affect the choice of foundation type.

From a geotechnical point of view, seismicity in the municipality is very low—characterised by low seismic activity and an insignificant maximum magnitude—so it does not impose any relevant restrictions on structural design. However, given the karst nature of the calcareous subsoil, it is essential to verify the possible presence of cavities or karst-related phenomena before formulating any foundation project. The non-clayey nature of the substrate rules out risks of expansivity, so the main focus should be on the investigation and monitoring of karst as a priority factor.
