Estudio geotécnico in Corbera

In Corbera, the dominant subsoil is formed mainly by fine sands and silts, which affects a moderate bearing capacity and a high permeability of the ground. This type of soil requires special attention when selecting the type of foundation, as its behaviour may be susceptible to differential settlement, particularly under concentrated loads. The minor presence of clays and hard marls, as well as of compacted gravels, may provide localised areas of greater resistance, but it does not represent the general condition across the municipality. A geotechnical study is therefore recommended to identify zones with possible masses of water or soft soils, optimising the foundation’s level of support.

Seismic activity in Corbera is very low, with hardly any recorded events every 30 years and a very low maximum magnitude (Mmax 1.7), so seismicity does not constitute a relevant constraint in structural design. However, as a marginal calcareous substratum is present and there is a risk of karstification, it is essential to check for cavities or dissolutions before founding, since these phenomena can severely affect the stability and durability of structures. The main risk is the possible presence of subterranean karst cavities, which must be assessed in detail in the geotechnical study.
