Estudio geotécnico in Barcarrota

In Barcarrota, the predominant subsoil is composed of sandstones, conglomerates and flysch, accounting for more than half of the formations, together with the significant presence of granite, gneiss and igneous rocks. These lithologies offer high-resistance properties and generally low deformability, which implies favourable bearing capacity for shallow and deep foundations. However, the impermeable nature or low permeability of these materials may lead to superficial aquifers in localised areas, an aspect to take into account to avoid moisture-related problems in substructures.

Seismicity in Barcarrota is very low, as evidenced by the scarcity of detected events and a low maximum magnitude. On the other hand, the possible presence of karstic phenomena due to the lithology of the area requires thorough verification before the design and execution of foundations, as it could affect ground stability. The risk from expansiveness is ruled out thanks to the absence of clayey soils, meaning that the main focus should be on investigating karstic cavities before any foundation work.
