Estudio geotécnico in Viñuela

In the municipality of Viñuela, soils formed by phyllites and schists predominate, covering most of the territory. These materials generally show low permeability, influencing the retention of surface water but providing a foundation with good bearing capacity for shallow (direct) foundations, provided that adequate compaction is ensured. The scarce occurrences of gravel and compact sands may also offer favourable points for founding, whereas the fine sands and silts present in smaller proportions require caution due to their compressibility and possible presence of moisture at the surface.

With regard to seismicity, Viñuela is characterised by a moderate level, with 14 recorded events over the last 30 years and a maximum magnitude that does not exceed 3.7, implying a low seismic constraint for structural design. The substrate does not include expansive clays, so the risk of expansivity in foundations can be ruled out. In this context, the main geotechnical consideration focuses on the assessment of density and the possible presence of shallow aquifers at the foundation level.
