Estudio geotécnico in Fonollosa

In the municipality of Fonollosa, the predominant geological substrate is composed of sandstones, conglomerates and flysch, which positively influences the ground’s stability and bearing capacity. These materials usually exhibit adequate stiffness and strength to support conventional buildings, making them suitable for a range of shallow foundation solutions. However, the low permeability of these formations may lead to the localised presence of shallow aquifers; this is something that should be checked in order to avoid adverse effects from the groundwater level in the design of the structural base.

Seismicity in Fonollosa is considered to be very low, with only a single reported event over three decades and a maximum magnitude of 1.5, so this factor does not condition the structural design. The soil type analysis confirms the absence of expansive clayey soils, ruling out risks associated with expansivity. Thus, the main constraint for the geotechnical study in the area lies in the localised verification of permeability and the presence of surface water, rather than in structural or seismic factors.
