Estudio geotécnico in Santo Domingo de la Calzada

In Santo Domingo de la Calzada, the dominant geological substrate is mainly made up of sandstones, conglomerates and flysch, accompanied by frequent deposits of compact gravels and fine sands with silts. This composition provides soils with acceptable bearing capacity, although the low permeability typical of these formations suggests the possible presence of confined aquifers at depth, which may condition the optimal foundation type, particularly in larger-scale projects.

Seismic activity in the municipality is very low, with only a single recorded event in the last 30 years and a maximum magnitude of 1.5, which means it is reasonable to consider seismicity as a secondary constraint for structural design. As the substrate is non-clayey, the problem associated with ground expansivity is ruled out. The determining factor in technical decision-making will be the proper hydrogeological characterisation of the subsurface, particularly with a view to interactions with possible aquifer levels and the management of groundwater during deep excavations.
