Estudio geotécnico in Pobla de Vallbona, the

In the Pobla de Vallbona, deposits of fine sands and silts predominate, forming a characteristic substrate with a medium-to-fine texture. These formations tend to be poorly cohesive and, in general, exhibit low bearing-capacity behaviour, requiring special attention when sizing foundations, particularly in projects involving significant loading. The permeability of these soils is low; however, shallow aquifers may be found in certain areas, which affects drainage and may increase the risk of dampness-related pathologies if the groundwater table level is not appropriately controlled.

With regard to specific geotechnical risks, seismicity in the Pobla de Vallbona is moderate, as indicated by the 27 events recorded over 30 years and a maximum magnitude value of 3.4, remaining well below critical levels for structural design. Although subordinate expansive clays are identified, their effect is limited and geographically constrained, since they are usually located in areas with climatic conditions that are less likely to present serious expansivity problems. The main geotechnical factor to consider will be the low bearing capacity of the silts and sands, particularly where the presence of water may further alter their properties.
