Estudio geotécnico in Campillos

In the municipality of Campillos, the ground is made up mainly of sandstones, conglomerates and flysch, which account for more than half of the materials present. These soils, combined with a secondary presence of fine sands, silts, gravels and compact sands, usually provide a good bearing capacity, although their heterogeneity may require a specific assessment to ensure uniformity of the foundations. Areas where limestones, dolomites and marbles predominate can locally influence the response of the subsoil, while the occasional existence of water bodies or shallow aquifers suggests paying attention to controlling the groundwater level in deep foundation works.

The seismicity in Campillos is high, with 199 recorded events over thirty years, although the maximum magnitude observed is moderate (Mmax 4.3); this means that the ground’s capacity to absorb seismic effects must be analysed for any relevant structural project. On the other hand, the possibility of developing karst phenomena associated with the calcareous formations requires prior checking of the condition of the subsoil before designing or carrying out the foundations, thereby ruling out dissolutive cavities that could compromise stability. Thanks to the absence of expansive clayey materials, no risk of expansivity is expected, leaving the karst factor and seismicity as the main geotechnical conditioning factors in the area.
