Estudio geotécnico in Jadraque

In Jadraque, the predominant geological substratum is composed of limestones, dolomites and marbles, which make up the majority of the local soils. These materials are recognised for their high bearing capacity and enable efficient direct foundations; however, the occasional presence of sandstones and conglomerates, together with specific levels of compact gravel and sand, may locally condition the mechanical characteristics to be considered in the geotechnical study. In addition, extensive, highly permeable aquifers entail special attention to controlling groundwater level drawdowns and potential effects on the stability of foundations.

With regard to natural hazards, the seismicity of Jadraque is significant, having recorded more than 150 events over 30 years and a maximum magnitude of 4.6, which makes it essential to incorporate seismic-resistant criteria into structural design. Given the predominance of carbonate materials, it is essential to verify the presence of karst before carrying out any foundation works, as the evolution of cavities can affect the safety of the building. The subordinated occurrence of expansive clays, although limited, requires a local assessment to avoid swelling-related problems in specific situations. The main factor conditioning the geotechnical study in Jadraque is the possible combined karst activity, together with the requirements arising from local seismicity.
