Estudio geotécnico in Santa Oliva

In Santa Oliva, gravel and compacted sands predominate by a wide margin, accompanied occasionally by calcareous formations such as limestones, dolomites and marbles. These lithologies often show low permeability at the surface, although they may host aquifers at depth. In general, the ground conditions favour a good bearing capacity for various types of shallow foundations, provided that the homogeneity and degree of compaction of the granular deposits are verified.

Seismic activity in the municipality is very low, with only 3 events in 30 years and a moderate maximum magnitude, so seismic risk is not relevant for structural design. However, the presence of calcareous ground requires checking for karst processes before founding, as these could affect the safety and stability of the building. The absence of clayey soils rules out the risk of expansivity, with karst being the main geotechnical factor to assess in the area around Santa Oliva.
