Estudio geotécnico in Vila de Cruces

In Vila de Cruces, the subsoils are predominantly formed by slates and schists, followed by the presence of sandstones, conglomerates and flysch. These metamorphic and sedimentary materials generally exhibit good load-bearing capacity, making them suitable for conventional shallow foundations, except in areas that are very altered or fractured, where a targeted assessment is recommended. The limited natural permeability of these ground conditions implies a low risk of settlement due to leaching, although shallow aquifers may be present in certain areas, which may require appropriate management of groundwater during the excavation and foundation phases.

Seismicity in Vila de Cruces is classified as moderate, with 14 recorded events over the last 30 years and a maximum magnitude of 2.4; therefore the seismic risk is low and, in principle, does not significantly condition structural design. Since the dominant subsoil is not clayey, the risk of expansiveness is ruled out, favouring greater predictability of ground behaviour. Overall, the main characteristic that governs geotechnical studies in this municipality is the fissured nature of the slates and schists, which must be analysed to ensure stability and proper foundation sizing.
