Estudio geotécnico in Cantalejo

In Cantalejo, the geotechnical subsoil is formed mostly by compacted gravels and sands, complemented by smaller proportions of sandstones, conglomerates and flysch, as well as limestones, dolomites and marbles. These materials present favourable behaviour for shallow foundations, since the compacted gravels and sands provide good bearing capacity and low compressibility. The extent of these formations and their limited permeability are advantageous for controlling settlement and avoiding problems associated with shallow groundwater levels. The limestones and dolomites, although less frequent, require particular attention due to their possible relationship with karstic phenomena.

Seismicity within the municipal term of Cantalejo is very low, with minimal activity and low magnitudes, so it does not constitute a limiting factor in the geotechnical design of foundations. Nevertheless, the presence of karst must be verified before carrying out any foundation in areas of limestones and dolomites, as the development of cavities may affect ground stability. The absence of expansive clays eliminates the risk of volumetric movements due to expansivity. The main geotechnical precaution in Cantalejo lies in controlling any potential karstic formations in order to guarantee structural safety.
