Estudio geotécnico in Turégano

In Turégano, a substratum of slates and schists predominates, providing a solid base and high compactness for foundations, although its low permeability influences the drainage of groundwater. Compact gravels and sands, which occur occasionally, offer good conditions for bearing capacity, while sandstones, conglomerates and flysch contribute to a lithological diversity that must be well characterised in any geotechnical study prior to design. The low presence of limestones and dolomites reduces, though it does not eliminate, the risk of alteration due to dissolution; therefore, precise identification of the support layer is essential for determining the optimal foundation type.

The area shows high seismicity, with more than 150 recorded events and a maximum magnitude of 4.7, which requires that structural design and foundation solutions consider seismic actions in accordance with current regulations. Although the substratum is not clayey and rules out the risk of expansivity, the possible existence of karst processes must be verified before executing foundations, given the occasional occurrence of carbonate materials in the subsoil. In conclusion, the main constraint for a geotechnical study in Turégano lies in the combined seismicity with the need to rule out local karst phenomena.
