Estudio geotécnico in Paredes de Nava

In Paredes de Nava, the dominant subsoil is composed mainly of compact gravels and sands, representing close to 76% of the soils present. These coarse-grained materials generally offer a high bearing capacity, which allows conventional shallow foundation solutions in most cases. The occasional presence of water bodies and small proportions of fine sands, silts, sandstones, conglomerates and slates suggests the need for localised analyses to avoid areas of lower density or potentially compressible materials; however, in general, the surroundings favour standard shallow foundations.

As for geotechnical risks, seismicity is notable for the area, with 57 events in 30 years and a maximum magnitude of 4; therefore, although critical values are not reached, it is a factor to be integrated into structural design to ensure seismic safety. The risk from expansivity is low, since the expansive clays present are subordinate or located in climatic areas that do not favour their development, minimising the likelihood of swelling-related problems. Thus, the main constraint for the geotechnical study in Paredes de Nava is the characterisation and point-by-point distribution of the granular units, particularly with regard to the possible presence of low-density or saturated zones.
