Geotechnical study in La Codosera

In La Codosera, the dominant subsoil is formed by phyllites and schists, metamorphic materials characterised by low permeability and high consistency. As these soils are generally impermeable, they provide favourable conditions for shallow foundations since they offer adequate bearing capacity and limited susceptibility to deformability-related problems, which simplifies the design of the supporting structure. However, the presence of occasional shallow aquifers in altered zones may require special attention to drainage management during foundation construction.

The recorded seismic activity in La Codosera is notable, with 52 events over 30 years and a maximum magnitude (Mmax) of 4,4, although it does not exceed the threshold requiring mandatory consideration for seismic structural design. The non-clayey subsoil completely rules out the risk of expansivity, favouring the dimensional stability of the ground. The main conditioning factor in the area is the need for an adequate geotechnical study of the local hydrogeological conditions, together with control of infiltration, with seismicity being less relevant.
