Estudio geotécnico in El Bonillo

In El Bonillo, the predominant geological substrate is composed of limestones, dolomites and marbles, which determines the presence of highly competent soils with good bearing capacity for foundations. These compact materials facilitate the transfer of loads to the ground and, together with the existence of moderately permeable aquifers, provide favourable conditions for the execution of shallow or deep foundations, depending on the project requirements and the useful depth of the substrate.

Seismic activity in El Bonillo is moderate, with 32 recorded events over the last 30 years and a maximum magnitude of 2.5, which implies a seismic constraint that is of little relevance for the usual structural design. Although the expansiveness of the clays is classified as subordinate to or associated with climatic zones where their activity is reduced, local verification of the presence of expansive clays remains advisable. In summary, the main geotechnical constraint in El Bonillo is linked to the detailed characterisation of the carbonate materials and the point-by-point confirmation of the absence of zones with potentially expansive clays.
