Estudio geotécnico in Madrigueras

In Madrigueras, geological substrates formed by limestones, dolomites and marbles predominate, constituting more than 95% of the ground. These materials are characterised by their high strength and low compressibility, normally providing excellent bearing capacity for the foundations of buildings, although local compaction and lithological continuity must be verified. Compact gravel and sand are only residual, so it is unlikely that they will significantly condition the foundation typology. The low permeability of these substrates usually limits the surface circulation of water, although aquifers may exist at depth.

The level of seismicity in Madrigueras is considered very low, with only two recorded events over thirty years, and a maximum magnitude limited to 1.7, which means that the seismic hazard is practically negligible for structural design. Nevertheless, the presence of karstification in the limestones and dolomites requires careful analysis of the possible existence of cavities or dissolutions before carrying out any foundation work, as these could generate differential settlements. The subordinate presence of expansive clays in non-problematic climatic zones reduces the risk of pathologies linked to swelling. The main geotechnical constraint to be considered will be the detailed verification of karst processes in the ground.
