Estudio geotécnico in Arbeca

In the municipality of Arbeca, soils formed by sandstones, conglomerates and flysch predominate, accounting for approximately 87.5% of the substrate. These materials, together with the occasional presence of gravel and compact sands, provide good bearing capacity for shallow foundations, which facilitates conventional solutions in most cases. The low permeability of these formations fundamentally limits infiltration, benefiting the stability of the foundations, although it is advisable to consider possible shallow aquifers during excavation or drainage phases.

Seismicity in Arbeca is very low, with a record of just 9 events in the last 30 years and a maximum magnitude of 2, so this factor does not represent a relevant concern in structural design. The absence of clayey substrata rules out risks associated with expansive soils, and there are no indications of karst processes in the area. In conclusion, geotechnical control in Arbeca focuses mainly on identifying permeable levels and conducting lithological characterisation, with no significant risks associated with expansivity or seismic activity.
