Geotechnical study in Lora del Río

In Lora del Río, the predominant subsoil is largely composed of fine sands and silts, accompanied by the presence of slates, schists and various calcareous formations such as limestones, dolomites and marbles. This combination results in variable bearing capacity, with areas suitable for shallow foundations due to the compactness of the gravels and sands, whereas areas with silt may require additional considerations owing to their lower strength. It is essential to characterise the local geotechnical subsoil in order to guarantee foundation stability, particularly by avoiding support on possible masses of water or soils with low compactness.

Seismic activity in the municipality is very low, with only two events of low magnitude over thirty years, which minimises the influence of earthquakes on structural design. However, given the occasional presence of carbonated materials such as limestones and dolomites, it is a priority to verify the existence of karst processes before carrying out foundations, as these can affect ground stability. The non-clayey substrate eliminates the risk of expansivity, the main geotechnical limiting factor being the possible presence of karstification.
