Estudio geotécnico in Granollers

In Granollers, the dominant subsoil is made up mostly of sandstones, conglomerates and flysch, which provides a generally competent foundation for shallow foundations. Fine sands and silts, which occur occasionally, have a moderate bearing capacity but require assessment of their compactness, whereas compact gravels and sands, although less common, offer excellent ground-support characteristics. The prevalence of extensive aquifers and their high permeability means that control of the groundwater level is a fundamental aspect for foundation design, particularly in areas close to watercourses.

From a seismic standpoint, Granollers shows very low hazard, with a single event over 30 years and a maximum recorded magnitude of 2.3, so this factor does not condition the structural design. The absence of clayey strata eliminates the risk of expansiveness, and there is no karst-related problem either. The main technical constraint for geotechnical studies in this municipality lies primarily in the ground’s permeability and the control of groundwater during the execution of the foundations.
