Estudio geotécnico in Getafe

In Getafe, soils predominantly formed by sandstones, conglomerates and flysch prevail, which generally ensures adequate bearing capacity for building and civil engineering works. Nevertheless, the occasional presence of limestones, dolomites and marbles introduces localised zones of greater stiffness, and, to a lesser extent, the occurrence of compacted gravels and sands provides favourable conditions for foundations. Areas with gypsum, anhydrite and salts represent a risk associated with dissolution processes, so they require thorough geotechnical studies to rule out problems in shallow or deep foundations.

Seismicity in Getafe is very low, with a maximum of five events over 30 years and a magnitude below 3, which implies that seismic actions are usually not relevant in design. However, since karst is present in the area, it is essential to carry out specific investigations to verify ground stability against this phenomenon before designing the foundation. As the main conditioning factor of the geotechnical study, attention should be paid to the possible impact of karst and to specific zones with gypsum or soluble salts, especially in projects located in areas underlain by calcareous or gypsiferous substrate.
