Estudio geotécnico in Santa Eugènia de Berga

In Santa Eugènia de Berga, white or soft expansive clays predominate, which constitute the majority of the subsoil, although compact gravels and sands are found sporadically. The dominance of low-compaction materials implies that the ground bearing capacity may be limited, especially for high loads; therefore, foundation solutions must be adapted according to these characteristics. Likewise, the low permeability of these formations makes it possible for superficial aquifers to exist, which is why drainage and water control should be considered in any geotechnical intervention.

With regard to seismicity, Santa Eugènia de Berga exhibits very low seismic activity, with only 5 events in the last 30 years and a maximum magnitude of 1.6, which minimises the seismic design requirement for structures. Nevertheless, the potential presence of karst must be carefully investigated before carrying out any foundation, as it can significantly affect the stability and durability of the building. The main constraint for geotechnical projects in this area is therefore the possible occurrence of karst processes, so its identification and detailed assessment should be prioritised in the geotechnical study.
