Estudio geotécnico in Algeciras

In Algeciras, soils formed by sandstones, conglomerates and flysch predominate, complemented by limestones, dolomites and marbles in a significant proportion. These lithologies generally provide adequate bearing capacity for most types of shallow or semi-deep foundation, although the occasional presence of overconsolidated clays and marls may require a targeted review of shear strength and, potentially, the need for special foundations in localised areas. Permeability is low, although shallow aquifers may be found in specific zones, which can influence the choice of foundation type and construction methods to avoid problems arising from water.

Seismicity in Algeciras is very low, with only two recorded events in the last thirty years and a low maximum magnitude of 2.3. There are no risks associated with karstic or expansive processes, since the substrate is not clayey and this rules out the danger of expansivity. The main requirement for geotechnical studies in this municipality is the proper characterisation of the predominant hard materials, as well as the delimitation of areas with possible aquifers or localised soft soils, in order to guarantee safe and durable foundation solutions.
