Estudio geotécnico in Uceda

In the municipality of Uceda, the substrata of slates and schists predominate, followed by sandstones, conglomerates and flysch, materials which generally exhibit low to very low permeability. This type of soil restricts the infiltration of water and can lead to the presence of superficial aquifers in certain areas. For building projects, the bearing capacity of these materials is usually sufficient, although the presence of water-mass zones may require specific investigations to verify ground homogeneity and avoid areas with possible hydrostatic thrust or anomalous slopes. A detailed geotechnical study is essential to determine the depth and the most suitable type of foundation for each plot, with particular attention to the transitions between discordant materials.

In terms of natural hazards, Uceda records significant seismicity, with 200 events in the last 30 years and a maximum magnitude of 4.6, which means that any structural project must consider seismic actions in its design in accordance with the applicable regulations. The non-clayey substratum eliminates the risk of expansivity, but the presence—although infrequent—of limestones and dolomites introduces the possibility of karstification, a phenomenon which must be verified before executing any foundation in order to rule out cavities, sinkholes or voids affected by dissolution. The main ground constraint in Uceda lies in the appropriate characterisation of the karst and in incorporating seismic requirements at the design stage.
