Estudio geotécnico in El Burgo de Ebro

In El Burgo de Ebro, the predominant ground conditions consist of water bodies and alluvial deposits, mainly fine sands, silts and, to a lesser extent, compact gravels and sands. This composition indicates high permeability and the presence of productive aquifers, which is beneficial for drainage, but requires detailed studies of the ground’s bearing capacity. The foundations will have to be adapted according to the local grain-size variability and must avoid direct support on areas of loose sands or silts, where stability may be compromised.

The area experiences notable seismicity, with 68 events in the last 30 years and a maximum magnitude of 4.8, so it is essential to include seismic considerations in the structural design. In addition, there is susceptibility to karst processes, so it is essential to verify the presence of voids or dissolution before carrying out foundation works. Although expansive clays have a subordinate presence, the need for specific located controls is not ruled out. The main geotechnical constraint is the combination of karst risk and seismic design requirements, both critical determinants for the safety of the foundations.
