Geotechnical study in Vera

In Vera, soils of fine sands and silts predominate, occurring in more than half of the territory, which implies variable bearing capacity and the need for specific geotechnical control to determine the depth and type of foundation suitable for each plot. The significant presence of carbonate materials such as limestones, dolomites and marbles, as well as compact gravels and sands, usually provides good mechanical properties where they outcrop, facilitating shallow foundations and providing structural safety, particularly outside areas with strata of compressible silts or fill materials.

Seismicity in Vera is classified as moderate, with 11 recorded events over 30 years and a low maximum magnitude (Mmax 2.5), so seismic risk does not represent a relevant structural constraint in the design of buildings. The absence of an underlying clay bed eliminates concerns about soil expansivity, allowing foundations to be designed without the associated risk of swelling or shrinkage. The main factor to consider in the geotechnical study for this municipality is the variability of grain size and the localised presence of compressible layers, requiring detailed investigation to ensure the foundation’s stability.
