Estudio geotécnico in Sabadell

In Sabadell, the subsoil is made up mostly of sandstones, conglomerates and flysch, accompanied in significant proportions by fine sands, silts, as well as gravel and compacted sands. These materials are characterised by providing adequate bearing capacity, which favours versatile options for shallow foundations in most cases. Low surface permeability limits the presence of water, although aquifers may occur at greater depths; this is a relevant aspect to consider for basements or for buildings with drainage problems.

The municipality has very low seismicity, reflected in just 3 events over 30 years and a moderate maximum magnitude of 2.9, so seismic requirements do not condition structural design in the area. As it has a non-clayey substratum, the risk of expansivity is ruled out in typical foundation ground conditions. Thus, the determining factor for the geotechnical study in Sabadell lies mainly in the precise characterisation of granular deposits and the point-by-point assessment of any possible deep aquifers.
