Estudio geotécnico in Molins de Rei

In Molins de Rei, the predominant subsoil is made up of slates and schists, which ensures favourable bearing capacity for direct foundations in most cases. In addition, the occasional presence of sandstones and conglomerates contributes to ground stability, while deposits of compact gravel and sand provide acceptable conditions for bearing, although local homogeneity and compaction must be assessed. The low frequency of fine sands, silts and carbonatic rocks implies that compressible soils or soils with a risk of dissolution are not significant for most of the municipality.

As regards seismic hazard, Molins de Rei has very low seismicity, with scarcely one recorded event every 30 years and a maximum magnitude of 2.5, placing it among the areas with the lowest seismic risk. The dominant subsoil is not clayey, which rules out problems associated with soil expansivity. There are no signs of significant karstification in the area, so the main geotechnical conditioning factor will be the mechanical characterisation of the rock subsoil to determine the support properties and any potential planes of weakness.
