Estudio geotécnico in Villaseca de la Sagra

In Villaseca de la Sagra, limestone, dolomites and marbles predominate as geological substrate, generally competent materials that usually provide a high bearing capacity for shallow foundations. The significant presence of masses of water indicates areas with extensive and discontinuous aquifers, which may influence the groundwater levels and the chemical aggressiveness of the water towards calcareous materials. In addition, although to a lesser extent, compacted gravels and sands are also present, which likewise provide good support conditions for the foundation, and some levels of sandstones and conglomerates, whose strength is generally favourable.

The area shows high seismicity, with 200 events over 30 years and a maximum magnitude (Mmax) of 5.1, so this factor must necessarily be taken into account in structural design. The possible existence of karst in the calcareous substrate makes it essential to verify the presence of cavities or dissolution before designing foundations, as these may compromise ground stability. The risk associated with expansive clays is limited, due to their subordinate distribution and location in areas that are not particularly problematic, but it should not be entirely disregarded. Thus, the main geotechnical constraint is related to the need to check for kárstic processes and the seismic action on the foundation area.
