Estudio geotécnico in Muskiz

In Muskiz, the subsoil is dominated by limestones, dolomites and marbles, together with a significant presence of sandstones, conglomerates and flysch. This lithic composition generally provides good bearing capacity, although the local heterogeneity of the flysch may require specific assessments. The predominance of carbonate formations makes it common to find a competent stratum for foundations, although the limited permeability of these materials suggests the possible existence of localised shallow aquifers, which must be considered when selecting the foundation solution.

The recorded seismic activity in Muskiz is very low, with a single event over 30 years and a maximum magnitude of 1.7, which minimises the influence of seismicity on structural design. However, the presence of carbonate materials makes it necessary to verify the existence of karst phenomena before constructing foundations, as dissolution and the presence of voids can affect ground stability. The absence of clayey subsoil eliminates the risk of shrink–swell behaviour, so the most relevant geotechnical factor will be the possible impact of karst in the project area.
