Estudio geotécnico in Carrión de los Condes

In Carrión de los Condes, the predominant subsoil is composed of compact gravels and sands, representing around 85% of the soils present in the locality. This type of granular material generally provides a good bearing capacity for shallow foundations, which favours structural stability. Occasional areas of masses of water are detected, and the presence of sandstones, conglomerates and flysch, as well as fine sands and silts, is infrequent; these may require targeted studies, although they do not represent the general soil context. The prevailing low permeability limits the migration of water, but there is the possibility of finding aquifers at depth, which is relevant for deep foundations.

From the seismic point of view, Carrión de los Condes exhibits notable seismicity with 57 events over 30 years, although with a moderately low maximum magnitude (Mmax 4), which implies the need to consider seismic actions in structural design. The risk due to expansivity is low, since expansive clays occur only in a subordinate or localised way in climatic areas that are not particularly problematic. The main constraint in Carrión de los Condes is the adequate characterisation of the bearing level, with particular attention to avoiding areas with the presence of water and carrying out a specific assessment where expansive clays are identified in the foundation setting.
