Estudio geotécnico in San Martín de la Vega

In San Martín de la Vega, carbonate materials predominate, such as limestones, dolomites and marbles, which form a firm substratum with a high bearing capacity for shallow and deep foundations. The occasional presence of gypsum, anhydrite and salts implies a potential risk of dissolution, especially in areas close to masses of water or where the water table is high. The aquifers present in the municipality are extensive and highly productive, which can generate significant underground flows that must be assessed before the execution of any foundation.

Local seismicity is very low, with only 7 events over 30 years and a maximum magnitude of 3.3, so it does not represent a relevant constraint for structural design. However, given the pronounced karstic nature of the limestones and dolomites, it is essential to verify the existence of cavities before building, as these can undermine ground stability. The non-clayey substratum rules out the risk of expansive soils, placing karst and the possible dissolution of gypsum as the main factors to be controlled in the geotechnical study.
