Estudio geotécnico in The Campana

In the municipality of La Campana, the subsoil is composed mainly of limestones, dolomites and marbles, which make up more than 94% of the substrate, showing competent behaviour and rock with high bearing capacity for foundations. Overconsolidated clays and marls appear only sporadically and do not condition the general behaviour of the ground. These carbonate materials typically provide low permeability at the surface, although they may contain relevant aquifers at depth; therefore, at a superficial level, they allow robust and stable direct foundations in most cases.

The seismicity recorded in La Campana is very low, with only a minor event in the reference period and with limited magnitude; as a result, the seismic hazard is practically negligible in structural design. It is worth noting the presence of risks associated with karst development in the carbonate formations, so it is essential to verify the existence of cavities or dissolution before designing the foundation. The fact that the substrate is not clayey also rules out the risk of expansiveness, identifying the control and study of karst as the main local geotechnical constraint.
