Estudio geotécnico in Medina de Rioseco

In Medina de Rioseco, substrates formed by compact gravels and sands predominate, as well as carbonated materials such as limestones, dolomites and marbles. These soils offer good bearing capacity conditions for shallow foundations, allowing, in most cases, the construction of isolated footings or rafts, although it is always advisable to confirm the local relative density. The occasional presence of gypsum, anhydrite and salts introduces a potential risk of dissolution, which may affect the long-term stability of foundations if they are founded on this type of material.

The municipality is located in an area of high seismicity, with 200 recorded events over 30 years and a maximum magnitude of 4.7, which requires considering specific seismic-resistant criteria in geotechnical and structural design. In addition, the existence of carbonated formations implies a risk of karstification, so it is essential to verify the presence of cavities or underground dissolutions before defining the foundation. As it is a non-clayey substrate, the risk of expansivity is ruled out. The main constraint in Medina de Rioseco is related both to seismic risk and to the possible presence of karst-related phenomena.
