Estudio geotécnico in Pedrajas de San Esteban

In Pedrajas de San Esteban, compact gravel and sands predominate, providing soils with a good bearing capacity suitable for most shallow foundations. The occasional presence of gypsum, anhydrite and salts introduces a potential dissolution risk that is important to consider when defining the foundation type and depth, especially in areas where these materials crop out. In addition, the existence of water bodies in the subsoil makes it necessary to study the local hydrogeological conditions and the possible occurrence of aquifers during the execution of the geotechnical study.

Seismicity in the area is high, with more than 150 events recorded over three decades and a maximum magnitude of 4.7, which requires compliance with specific regulations in the structural design of new buildings. The possible presence of karst in the area requires detailed verification before carrying out any foundation, given the risk of subsidence or cavities. Although expansive clays exist, they appear subordinate and in contexts that normally do not pose a critical hazard; the main determining factor will be defined by the interaction between the karst risk and the possible dissolution of gypsum and salts at the site selected for construction.
