Estudio geotécnico in Sarrión

The municipality of Sarrión shows a predominance of sandstones, conglomerates and flysch, followed by associations of limestones, dolomites and marbles, as well as an occasional presence of gypsum, anhydrite and salts in the geological profile. These materials generally provide good bearing-capacity parameters; however, low-permeability formations may affect the drainage of water and, in the case of gypsum and salts, add certain risks associated with dissolution. For foundation design purposes, it is essential to assess the depth and composition of the load-bearing stratum to ensure stability and avoid bearing on levels with a significant presence of gypsum.

From the seismic standpoint, Sarrión’s seismicity is moderate, with 10 events over 30 years and a discrete maximum magnitude (Mmax 2.8), which minimises the influence of this factor on geotechnical design. The non-argillaceous substrate rules out the presence of expansive clays and, therefore, risks associated with heave or shrinkage. However, the potential existence of karst phenomena in the carbonate materials requires specific verification to rule out cavities or voids before founding, making this aspect the main constraint in local geotechnical studies.
