Estudio geotécnico in Valderrubio

In Valderrubio, fine sands and silts predominate; these make up the majority of the near-surface substrate, generally providing a moderate bearing capacity suitable for light buildings or residential use. Water bodies occur as occasional areas which, together with the localised zones of limestones, dolomites and marbles, as well as a low percentage of hard clays and marls, require precise characterisation to identify ground heterogeneity. The typically low permeability of these formations implies that attention should be paid to groundwater management in foundation projects, although at depth aquifers of significance may occur.

Seismicity in Valderrubio is very low, with only one significant event recorded in the last 30 years, although with an estimated maximum magnitude of 4.6, which means that structural analysis must include seismic criteria in the design. Since the predominant substrate is not clayey, the risk of expansiveness is ruled out, reducing potential differential movements due to volumetric changes. In conclusion, the main factor to consider in this municipality is the correct assessment of textural alternations and soil permeability in order to ensure a safe and efficient foundation.
