Estudio geotécnico in Bargas

Within the municipal term of Bargas, water-bearing masses predominate, followed by deposits of sandstone, conglomerates and flysch, as well as occasional outcrops of limestones, dolomites and marbles, together with slates and schists to a lesser extent. Granular soils, such as compacted gravels and sands, are considered occasional, but they may provide good conditions for establishing shallow foundations thanks to their adequate bearing capacity. However, lithological alternation and the presence of aquifers with moderate permeability make detailed characterisation of the ground profile advisable before defining the optimal foundation type.

The Bargas area shows high seismicity, with 200 recorded events over 30 years and a maximum magnitude (Mmax) of 5.1, which requires considering explicit seismic actions in the structural design of any building. Although expansive clays are not predominant, their local presence may influence the behaviour of shallow foundations, particularly in areas vulnerable to changes in moisture. The main geotechnical constraint in Bargas therefore lies in the need to adopt solutions that integrate both seismic risk and the local review of potentially expansive soils during the design phase.
