Estudio geotécnico in Leciñena

In Leciñena, the subsurface materials are predominantly limestones, dolomites and marbles, accompanied by significant proportions of gypsum, anhydrite and salts. This composition generally provides good bearing capacity, with the presence of gravels and compact sands being common, and, to a lesser extent, hard clays. However, the existence of gypsum and salts implies a potential risk of dissolution that must be analysed in detail in the prior studies for the foundation to avoid differential settlements or collapses. The high permeability of the local aquifers can condition deep foundation solutions in saturated areas.

The municipality has a notable level of seismicity, with 68 registered events over 30 years and a maximum magnitude of 4.8, which requires consideration of seismic actions in structural design. The non-clayey substrate rules out risks associated with expansiveness, while the absence of karst processes simplifies geotechnical planning. As the most relevant constraint, special attention must be paid to the behaviour of soils with gypsum and salts, together with compliance with the requirements for seismic loads, to ensure the safety and durability of the constructions.
