Estudio geotécnico in Ricla

In Ricla, the predominant geotechnical subsoil is mainly composed of compacted gravels and sands, providing a ground with good bearing capacity and suitable permeability, particularly useful for shallow foundations. The occasional presence of sandstones, conglomerates, flysch and, although to a lesser extent, limestones and dolomites, suggests variability in the ground’s response. It is also worth noting the occasional occurrence of gypsum, anhydrite and salts, materials whose risk of dissolution conditions the choice and protection of the foundation in localised areas, whereas the fine soils (fine sands and silts) require a site-specific study due to their potential compressibility.

Local seismicity is rated as notable, with 85 events recorded over three decades and a maximum magnitude of 2.8, although it does not reach critical levels for most structures. The absence of expansive clays and the predominance of a non-clayey subsoil rule out expansivity risks. However, it is essential to consider the possibility of karst-related phenomena linked to outcrops of limestone and gypsum; therefore, detailed verification of the risk of karstification is a key limiting factor for the feasibility and safety of the foundations in Ricla.
