Estudio geotécnico in Villanubla

In Villanubla, the dominant substrate is composed of limestones, dolomites and marbles, hard materials that provide excellent bearing capacity and a favourable environment for shallow and deep foundations. In addition, compacted gravels and sands appear in smaller proportions, useful for support provided that thickness and uniformity are verified. The occasional presence of gypsum, anhydrite and salts requires particular attention due to possible dissolution, which may affect the stability of any structure. Low surface permeability reduces the risk of differential settlements due to consolidation of soft soils.

Villanubla presents high seismic activity, with 200 events over 30 years and an estimated maximum magnitude of 4.7, which requires considering seismic action in the design of structures. The substrate is not made up of expansive clayey materials, so this risk is ruled out. However, since karst processes are developed within the limestones, it is critical to verify the karst before laying foundations, as the presence of cavities could condition the safety and durability of the building. The main local limiting factor is determined by the interaction between karst risk, appreciable seismicity and the possible alterability of the gypsum.
