Estudio geotécnico in Sonseca

In Sonseca, the dominant subsoil is made up mainly of granite, gneiss and other igneous rocks, which provides a solid and stable foundation for construction. These materials usually have a high bearing capacity, favouring shallow (direct) foundations and minimising the need for special solutions. Compact gravels and sands, although present in smaller proportions, provide good drainage conditions, while limestones and dolomites occur very infrequently and have little impact on the overall behaviour of the ground.

Seismicity in Sonseca shows high values, with more than 150 recorded events over 30 years and a maximum magnitude (Mmax) of 5.1; therefore, the structural design must incorporate seismic-resistant criteria to ensure the safety of buildings. The non-clayey subsoil rules out problems associated with soil expansiveness, allowing greater long-term stability. The main constraint for geotechnical studies in this municipality is the correct assessment of seismic actions on foundation solutions, given the ground characteristics and its notable seismic activity.
