Estudio geotécnico in Sobrado

In Sobrado, the subsoil is widely dominated by slates and schists, followed by sandstones, conglomerates and flysch, while the presence of granite, gneiss and other igneous rocks is occasional. These rocky materials, generally hardened and compact, provide good bearing capacity to the ground, which facilitates the selection of shallow foundations for most buildings. However, the low permeability of these formations may affect surface drainage and groundwater levels, which requires an appropriate prior geotechnical study to define the most suitable construction solutions.

Seismic activity in Sobrado is very low, with only 4 events over the last 30 years and a maximum magnitude of 2.2, so seismicity does not represent a determining aspect in structural design. Since the dominant substrate is not clayey, the geotechnical risk arising from expansive soils is ruled out. The main geotechnical constraint in the area lies in the occasional difficulty of managing surface and groundwater due to the low permeability of the materials, making it advisable to evaluate this in detail in every geotechnical study.
