Estudio geotécnico in Castilleja de Guzmán

In Castilleja de Guzmán, the dominant geological substratum is made up of limestones, dolomites and marbles, materials of high competence and good geotechnical performance. These soils, due to their stony nature, provide a high bearing capacity for conventional foundations and, generally, ensure favourable conditions for load transmission. The presence of discontinuous aquifers and moderate permeability must be taken into account in the design phase, as it may affect ground stability and drainage conditions. In this setting, the arrangement of shallow foundations is common, although a detailed geotechnical study is always recommended to avoid possible local heterogeneities.

Seismicity in the area is very low, with a single recorded event in the last 30 years and a maximum magnitude of 1.7, which implies a practically negligible seismic risk for structural design. The expansiveness analysis indicates the secondary and localised presence of non-expansive or dispersed clays in a non-clayey matrix, so the expansiveness risk is local and can be controlled through proper characterisation in situ. The main geotechnical constraint in Castilleja de Guzmán lies in the hydrogeological variability within the carbonated materials; accordingly, a specific study of the characteristics of the substratum is essential to optimise foundation design.
