Estudio geotécnico in Traspinedo

In Traspinedo, soils predominantly comprise gypsum, anhydrite and salts, as well as limestones, dolomites, marbles and compacted gravels. This composition implies variable bearing capacity, where foundation stability may be affected by the significant presence of soluble materials, especially gypsum, which poses a risk of dissolution in the presence of water. Compact gravels and sands provide good support for shallow foundations, whereas the occasional presence of silts or bodies of water requires particular care to avoid differential settlement and ensure the structure’s safety.

Seismicity in Traspinedo is high, with more than 200 events over 30 years and a maximum magnitude of 4.7, so it is essential to incorporate anti-seismic criteria into structural design. The karst risk must be investigated thoroughly, since dissolution of gypsum and other soluble materials can create voids susceptible to collapse, which severely conditions the choice of foundation type and depth. The non-clayey substrate rules out expansiveness risk, but the main geotechnical constraint in this municipality lies in gypsum dissolution processes and the high level of seismic activity.
