Estudio geotécnico in Flix

In Flix, sandstones, conglomerates and flysch predominate as subsoil materials, accompanied occasionally by layers of compact gravels and sands. These soils usually provide a good bearing capacity for shallow foundations, although a specific analysis is required due to the lithological variability that characterises these formations. Overall permeability is low, a situation that minimises the risk of internal erosion, but it may favour the presence of localised superficial aquifers, which is relevant for defining the foundation level and protection against groundwater.

Seismicity in the Flix area is very low, with only 4 events over 30 years and a maximum magnitude of 2.4, so it does not represent a significant constraint in structural design. The risk of expansiveness is ruled out as the subsoil is not clayey. However, the possible presence of karst-related processes associated with the prevailing lithologies is observed; therefore, it is essential to verify the existence of cavities or underground dissolution before defining any type of foundation. This final aspect constitutes the main geotechnical constraint to take into account in the municipality.
