Geotechnical study in Hinojosa del Duque

In Hinojosa del Duque, substrates of slate and schist predominate. These metamorphic materials give the ground a medium-to-high bearing capacity and generally homogeneous behaviour with respect to foundations. Fine sands and silts, as well as compact gravels, occur occasionally and may influence the choice of foundation type locally, although the rock formations dominate the geotechnical context, providing stability and reducing the presence of compressible or deformable zones.

Seismicity is very low, with only two recorded events in the last 30 years and a maximum magnitude of 2.3, so seismic risk is not a relevant constraint for structural design. As no clayey substrate is present, the existence of problems associated with expansiveness is ruled out, and no karstification phenomena have been identified in the municipality. The main factor to be considered will be the appropriate characterisation of the slate and schists in the borehole, ensuring that the foundations are constructed on competent materials.
