Estudio geotécnico in Olivença

In Olivenza, the predominant geological substrate is composed of slates and schists, followed by sandstones, conglomerates and flysch, which provides ground with characteristics that are generally competent in terms of bearing capacity. Hard clays and marls occur only in specific locations, while the presence of granite and other igneous rocks is of little significance. With regard to foundations, the low permeability of these materials favours the stability of buildings, although it may limit the discharge of surface water, which should be taken into account in the design of drainage systems associated with the structure.

Seismicity in Olivenza is at moderate levels, with 19 events recorded in recent decades and a maximum magnitude of 4.4, suggesting that this factor should be given due attention in structural studies. Although the substrate is not clayey and therefore the risk of expansivity is ruled out, the possible presence of karstification in the surrounding area requires thorough verification of the ground before any deep foundation work, as cavities or hidden instabilities may appear that could affect the safety of the project. Verification of karst forms the main geotechnical constraint in this municipality.
