Estudio geotécnico in Villanueva de los Castillejos

In Villanueva de los Castillejos, the subsoil is widely dominated by shales and schists, accompanied to a lesser extent by limestones, dolomites and marbles. These materials provide a generally competent foundation, with sufficient bearing capacity for various types of shallow foundations, although formations of fine sands and silts, present only occasionally, require particular attention due to their lower cohesion. The presence of granite and gneiss, despite being scarce, reinforces the area’s geotechnical stability, while the low permeability of most materials minimises the risk of differential settlement caused by groundwater.

Seismicity in the municipality is very low, with only 3 recorded events over 30 years and a maximum magnitude of 2, implying a minimal impact on earthquake-resistant design of buildings. The sub-stratum does not show any clay-like character, which eliminates concern regarding expansive behaviour. In addition, the absence of karst rules out the presence of risks associated with underground cavities. In summary, the main factor to consider in the geotechnical study in Villanueva de los Castillejos is the proper characterisation of the degree of fracturing of the shaly materials and the identification of any possible layers of sand or silt, rather than the presence of more significant geological hazards.
