Estudio geotécnico in Mancha Real

In Mancha Real, soils of sandstones, conglomerates and flysch predominate, followed by limestones, dolomites and marbles—materials that offer good bearing-capacity conditions and generally allow the construction of shallow or semi-deep direct foundations. The occasional presence of compact gravel and sand is favourable for transmitting loads, whereas clays and marls, although infrequent and overconsolidated, can be considered to have low deformability. The low permeability of most formations limits infiltration, although there is a possibility of finding shallow aquifers in some areas.

Regarding structural risks, seismicity in Mancha Real is very low, with low seismic activity and a maximum recorded magnitude of 3.1, which minimises the need for specific measures on account of this factor. The presence of a karstified environment is a critical aspect to assess, especially in areas of limestones and dolomites, as cavities may occur that affect foundation safety; therefore, it is essential to verify the presence of karst before the development of any project. As for expansivity, expansive clays appear subordinately or in areas with low climatic-risk, which reduces their direct impact. Verification of karst is the main local geotechnical constraint.
