Geotechnical study in Ribesalbes

In Ribesalbes, soils formed by sandstones, conglomerates and flysch predominate, followed by limestones, dolomites and marbles, together with the occasional presence of compacted gravels and sands. These lithologies provide adequate bearing capacity, although compaction and cohesion vary depending on the specific type of material present, making detailed characterisation advisable to define the most suitable foundation type. The formations exhibit low permeability at the surface, although they may host significant aquifers at depth, an aspect to be considered in the case of deep excavations.

From a geotechnical standpoint, Ribesalbes lies in an area of high seismicity, with 200 events recorded over thirty years and reaching a maximum magnitude of 4.7, which necessitates the incorporation of seismic-resistant criteria into the structural design. In addition, the existence of abundant carbonate materials implies the possibility of karst development; it is essential to verify the presence of cavities before constructing foundations in order to avoid the risks of subsidence. The absence of clays rules out expansion-related phenomena, so the main geotechnical constraint comes from seismic activity and the potential presence of karst processes.
