In Fuente Carreteros, fine sands and silts predominate, representing more than 75% of the soils present, followed in smaller proportions by gravels, compact sands and some calcareous formations. This type of substrate usually exhibits a medium bearing capacity, although the frequent presence of silts can limit the strength and stability of shallow foundations. In addition, the low permeability of these soils suggests the possibility of shallow aquifers, which may require further hydrogeological studies for building projects.

The municipality lies in an area of notable seismicity, recording 54 seismic events over the last 30 years and reaching a maximum magnitude of 4.6, which makes it essential to include seismic analysis in structural design. The main constraining factor is the presence of expansive clays that predominate; this increases the risk of foundation pathologies considerably due to volumetric changes in the soil. Specific geotechnical study characterisation is essential in order to prevent differential settlements and ensure safety against this expansive risk.
