Geotechnical study in Morales del Vino

In Morales del Vino, the ground is mainly composed of sandstones, conglomerates and flysch, representing the majority of the frequent substrates. These materials usually provide good bearing capacity, particularly when they are in a compact condition, which allows conventional shallow foundations in most cases. The limestones, dolomites and marbles that occur sporadically may present zones with varying mechanical characteristics, but, in general, the compact gravels and sands—although less common—are also suitable for direct foundation when their relative density is high. The predominance of low-permeability formations reduces the risk of problems associated with seepage and delayed settlement, although the local hydrological conditions must be studied in detail.

The seismicity in Morales del Vino is high, with 200 recorded events over the last 30 years and a maximum magnitude (Mmax) of 4.5; therefore, this aspect must be considered rigorously in structural and foundation design, incorporating the code seismic parameters when designing. There are no records of karst or any significant presence of expansive clay materials, so the risk of expansivity is ruled out. The main geotechnical constraint is determined by the requirement for calculations and foundation solutions that take account of the seismic actions specific to the locality.
