Estudio geotécnico in El Casar de Escalona

In El Casar de Escalona, the dominant soils correspond to sandstones, conglomerates and flysch, frequently accompanied by shales and schists. These materials usually provide sufficient bearing capacity for most types of shallow foundation, although the heterogeneous presence of layers may require specific studies of stratigraphy and compaction. On the other hand, the occasional occurrence of compacted gravels and sands provides additional favourable conditions, while the proximity of water bodies indicates the existence of local aquifers, which is an aspect that should be assessed during the development of the geotechnical study.

From the point of view of seismicity, the municipality shows a high level of seismic activity, with 200 events in the last 30 years and a maximum recorded magnitude of 5.1; this means that structural design must incorporate specific seismic requirements. The expansivity conditions suggest the presence of non-expansive or dispersive clays in a non-clayey matrix, which does not completely rule out the risk of expansivity, so a plot-by-plot targeted analysis is recommended. Therefore, the main technical precaution in El Casar de Escalona lies in appropriate seismic characterisation and in ruling out the local presence of clayey soils with potential expansion.
