Estudio geotécnico in Albinyana

In Albinyana, carbonate soils predominate, with a subsoil formed mainly by limestones, dolomites and marbles, which provides a good bearing capacity for shallow and deep foundations due to the high compactness and stiffness of these formations. On a localised basis, levels of compacted gravels and sands are found, as well as the minor presence of hard clays and hard marls, both of which generally show favourable mechanical behaviour. However, the low surface permeability and the possible existence of aquifers at depth require special attention during execution of the works, particularly with regard to drainage.

The area has very low seismicity, with only 6 recorded events over 30 years and a maximum magnitude of 2.1, so this aspect does not represent a relevant constraint for structural design. The non-clayey nature of the subsoil rules out risks associated with soil expansiveness. However, given the karstic character of the prevailing formations, it is essential to verify the presence and geometry of cavities before deciding on the foundation type, this being the main limiting factor in geotechnical studies for Albinyana.
