Estudio geotécnico in Ferreries

In Ferreries, the geological substrate is characterised mainly by the presence of limestones, dolomites and marbles, generally favouring a good bearing capacity for any type of shallow or deep foundation. The secondary occurrence of sandstones, conglomerates and some flysch also provides lithological variety, although with stable mechanical properties for building. The occasional appearance of fine sands and silts is limited and, therefore, its practical influence on the choice of foundation type is not very relevant.

Seismic activity in the area is moderate, with 24 events over 30 years and a maximum magnitude of 3.2, which does not represent a critical constraint in structural design. However, the karstified nature of the limestones and dolomites requires prior checking for possible cavities or subsidence before defining the most suitable foundation solution. Added to the absence of expansive clay soils, the main conditioning factor for geotechnical studies in Ferreries is verifying the karst risk in areas of possible development.
