Estudio geotécnico in Serrada

In Serrada, sandstone, conglomerate and flysch materials predominate, together making up more than 70% of the substratum. These soils provide a very good bearing capacity thanks to their granular composition, being especially favourable for foundations when they are in a compact state. The presence, although less frequent, of compact gravels and sands increases overall permeability, which can benefit the ground’s natural drainage and reduce the likelihood of moisture accumulation beneath structures.

The municipality shows high seismicity, with 200 events recorded in the last 30 years and a maximum magnitude (Mmax) of 4.7; this parameter makes seismic action a key aspect to be considered during the structural design phase. The possible presence of expansive clays, although secondary and also localised in areas without water deficit, notably reduces the risk associated with shrink–swell movements; however, it is advisable to pay attention to their punctual presence. The primary constraint in works in Serrada is seismic action, followed by the spot control of the presence of expansive clays.
