Geotechnical study in Puebla de Don Rodrigo

In Puebla de Don Rodrigo, formations of schists and slates predominate; these metamorphic materials exhibit characteristics of low permeability and high compactness. These soils, together with the occasional presence of gravels, compact sands, and a smaller proportion of sedimentary rocks such as sandstones and conglomerates, generally provide an adequate bearing capacity for most types of shallow foundations. However, the impermeable nature of the subsoil makes it essential to carefully consider the control of surface drainage and the point-specific presence of shallow aquifers during the geotechnical study.

Seismic activity in the municipality is classified as high, with more than 200 events in the last 30 years and a maximum recorded magnitude of 5.1, which means that seismicity must be considered without exception in every structural and foundation design. Since the dominant subsoil is not clayey, the risk of expansiveness is ruled out as a relevant factor. Therefore, seismicity is established as the main conditioning factor for preparing the geotechnical study in Puebla de Don Rodrigo.
