Estudio geotécnico in Villar de Rena

In Villar de Rena, the predominant presence of fine sands and silts, together with a smaller representation of sandstones, conglomerates, flysch and compact materials such as gravels, suggests a substrate characterised by variable grain size, with a predominance of low-plasticity cohesive soils and non-cohesive soils. This diversity implies that bearing capacity may vary significantly depending on location, although adequate behaviour for shallow foundations is generally to be expected in areas of compact sands. The low representativeness of hard clays limits problems related to compressibility, while the proximity of water masses must be assessed in order to avoid problems caused by a high groundwater level.

Seismicity in the municipality is notable, with 52 registered events over 30 years and a maximum magnitude (Mmax) of 4.4, which implies a seismic risk that must be studied though it does not reach critical values. No problems related to karstification or expansive clayey substrate are identified, thereby ruling out these conditioning factors. For all these reasons, the main aspect to consider in a local geotechnical study will be soil heterogeneity and control of the groundwater level in areas influenced by shallow aquifers, in addition to taking into account the recommendations for structures subjected to moderate seismicity.
