Estudio geotécnico in Ocaña

The municipality of Ocaña has a dominant substrate formed mainly by sandstones, conglomerates and flysch, with a significant presence of limestones, dolomites and marbles. These materials provide a good response in terms of bearing capacity, favouring solutions with shallow foundations in most situations. It is important to highlight the occasional presence of gypsum, anhydrite and salts, which may pose a risk of dissolution and must be identified precisely in the geotechnical study. In addition, extensive and productive aquifers reflect high permeability, which facilitates drainage of the ground and may condition excavation and support methods, particularly near water bodies.

With regard to additional risks, seismicity in Ocaña is very low (9 events in 30 years, Mmax 2.8), so it does not represent a relevant structural constraint. However, the potential local presence of expansive clays implies a recognised risk that must be analysed point by point, as it could affect the stability of foundations in those specific climatic areas. It is also essential to verify the possible influence of karst prior to foundation construction, due to the frequency of limestones and dolomites, to avoid subsidence or collapses. The main geotechnical constraint will be localised zones with swelling and the possible presence of karstic cavities.
