Estudio geotécnico in Illueca

In Illueca, soils of sandstones, conglomerates and flysch predominate, followed by slates and schists, which provides a generally competent substrate for foundation work, thanks to its good bearing capacity. Limestones, dolomites and marbles occur occasionally, and in a smaller proportion, compact gravels and sands are found; both types show adequate stability. As the formations are mostly impermeable or have low permeability, the presence of shallow aquifers is possible but limited, which may slightly affect the hydraulic behaviour of foundations at certain points.

Seismicity in Illueca is very low, with only 3 recorded events in the last 30 years and a maximum magnitude of 1.7, meaning that seismic hazard is practically negligible in structural design. However, since part of the territory includes limestones and dolomites, it is essential to verify the existence of karst-related phenomena before any foundation is carried out, as this factor can condition the safety and stability of structures. The risk of expansiveness is ruled out, since the substrate is not clayey. The main geotechnical constraint in Illueca is the possible presence of cavities or irregularities associated with karst.
