Estudio geotécnico in Gironella

In Gironella, geotechnical studies predominantly find soils formed by sandstones, conglomerates and flysch, characterised by their consistency and low surface permeability. These lithological units often offer a moderate to high bearing capacity, suitable for the foundation of all types of buildings, although it is essential to check compaction and the possible point presence of less competent layers. The formations observed may also contain deep aquifers, which should be identified to prevent unwanted drawdown of the groundwater table during construction.

As regards seismicity, Gironella experiences very low seismic activity, with only 5 recorded events and a maximum magnitude of 1.6 over recent decades, which significantly reduces the need to require special reinforcements in the earthquake-related structural design. With respect to expansiveness, although subordinate expansive clays are present, their influence is usually limited to specific areas or to zones with climatic conditions favourable for their activation. The determining factor for foundations will be the possible local presence of these clay layers and the characterisation of substrate permeability, rather than seismicity.
