Estudio geotécnico in Cadalso de los Vidrios

In Cadalso de los Vidrios, the dominant substrate is made up mainly of granite and gneiss, together with other igneous rocks, representing almost the entire ground. These materials provide excellent bearing capacity for foundations, although they may present some heterogeneity in terms of near-surface fracturing. Compact gravels and sands are uncommon and, although they also have good mechanical properties, they rarely appear as the dominant layer. The overall low permeability of these soils limits the migration of water, but it may allow local, shallow aquifers to occur in some areas.

Seismicity in the municipality is considered very low, with only 5 events over 30 years and a maximum magnitude of 3, which minimises the seismic impact on structural design. There are no risks associated with karst or expansivity, since the non-clayey substrate removes concerns regarding expansive soils. The most relevant factor for the geotechnical study in this locality is the assessment of fracturing in the bedrock and the correct identification of its mechanical characteristics before carrying out the foundations.
