Estudio geotécnico in Artana

In Artana, limestone, dolomites and marbles predominate as substrates, accompanied in also significant proportions by fine sands, silts, sandstones, conglomerates and flysch. This lithological diversity generally leads to good values of bearing capacity suitable for different typologies of shallow and deep foundations. However, the occasional presence of gypsum, anhydrite and salts introduces a dissolution risk under conditions involving the flow of water, which may affect stability if the design does not take this into account. In any case, it is essential to avoid direct foundation on these materials and on non-competent soft soils.

Seismic activity in Artana is very low, with only a single recorded event in the last 30 years and a maximum magnitude of 1.5, which allows seismicity to be ruled out as a relevant design constraint for the structural design. No risk of expansivity is identified either, given the predominantly non-clayey nature of the substrate. However, given the karstic origin of many limestones and dolomites in the area, it is essential to verify the presence of cavities and karstic dissolution processes before carrying out any foundations, since this is the main aspect to be considered in the geotechnical study for the municipality.
