Estudio geotécnico in Cerceda

In Cerceda, sedimentary materials such as sandstones, conglomerates and flysch predominate, accompanied in smaller proportions by slates, schists, granite and gneiss. These soil types, especially the siliciclastic and metamorphic ones, generally show high strength and stiffness, which benefits the ground bearing capacity and allows a wider range in the selection of foundation systems. However, the low permeability of these formations may lead to the localised presence of shallow aquifers, which should be checked in specific studies before carrying out foundations.

Seismicity in Cerceda is classified as moderate, with 16 events over 30 years and maximum magnitudes that do not exceed the critical threshold for conditioning structural design, so its influence on geotechnical conditions is limited. Since the subsoil is not clayey, the risk of soil expansiveness is ruled out as a conditioning factor for the project. In this context, the main factor to consider remains the detailed characterisation of the lithology and the possible presence of groundwater.
