Estudio geotécnico in Live

In Viver, the predominant substrate corresponds to limestones, dolomites and marbles, materials that cover most of the local geology and generally exhibit low near-surface permeability, although they may host aquifers at depth. The significant presence of gypsum, anhydrite and salts introduces the possibility of dissolution processes, which necessitates special attention when assessing ground stability and may limit bearing capacity in specific areas. The secondary presence of sandstones and conglomerates is rare and typically will only influence, in a punctual manner, the choice of foundation type, which requires a detailed analysis in order to adapt the design to possible local heterogeneities.

With regard to geotechnical risks, soil expansion can be ruled out, since the substrate is not clayey, eliminating the problematic issues associated with swelling. Seismicity is very low (3 events in 30 years, Mmax=2.7), so it does not represent a relevant constraint for structural design. However, the main geotechnical constraint in Viver is susceptibility to karst: the presence of cavities or dissolution must be verified before carrying out any foundation works, particularly in the sectors where gypsum and limestones crop out, due to the potential risk of subsidence or differential instability.
