Estudio geotécnico in Darro

In Darro, formations of limestones, dolomites and marbles predominate; these, together with the significant presence of gravels and compacted sands, make up a competent and stable substrate for building. Fine soils, such as sands and silts, occur only occasionally, whereas hard clays and marls account for a very small proportion. The bearing capacity in the area is generally high, allowing for shallow (direct) foundations unless there are zones where finer soils outcrop, in which case a more specific analysis will be necessary to avoid differential settlements.

Seismicity in Darro is very low, with only 6 recorded events over 30 years and a Mmax of 2.1, meaning that seismic risk is practically negligible in structural design. Nevertheless, the karstic nature of the limestone and dolomitic materials requires a detailed check for the presence of cavities or dissolution processes before carrying out any foundation, since this factor can significantly condition the behaviour of the ground. The absence of clayey strata rules out the risk of expansivity, consolidating karst as the main geotechnical factor to take into account in this municipality.
