Geotechnical study in Villamuriel de Cerrato

In Villamuriel de Cerrato, limestone, dolomite and marble soils predominate. These materials usually provide good bearing capacity for foundations, although voids may develop due to karst dissolution processes. Compact gravel and sand, which are less frequent, also offer favourable mechanical performance. The minor presence of gypsum, anhydrite and salts is notable, as it introduces potential dissolution risks that may affect the long-term stability of structures. The high permeability and the presence of extensive aquifers reinforce the need to carry out rigorous hydrogeological characterisation, especially in areas close to bodies of water or saline soils.

The record of 57 seismic events over the last 30 years, with a maximum magnitude of 4, indicates significant seismicity which, although not extreme, advises incorporating seismic criteria into the structural design of new buildings. Given the non-clayey substratum, the risk of expansivity is ruled out, allowing shallow foundations under usual conditions. The main geotechnical constraint in the area is the potential development of cavities due to karst processes and the interaction with zones of gypsum or salts. These aspects require detailed verification through a geotechnical study before carrying out any foundation works.
