Estudio geotécnico in Sencelles

In Sencelles, the subsoil is made up mainly of fine sands and silts, which occur very frequently and can provide moderate bearing capacity, suitable for buildings with conventional loads, provided that their compaction is controlled. In addition, the significant presence of limestones, dolomites and marbles increases the ground’s competence and allows the option of shallow foundations where the rock outcrops. It is important to mention the existence, albeit sporadic, of gypsum, anhydrite and salts, which may involve dissolution processes to take into account in foundation projects.

The seismic activity in the area is moderate, with 24 events recorded over 30 years and a maximum magnitude of 3.2, which indicates some local structural stability, although an appropriate seismic analysis must never be ruled out in building design. The non-clayey substratum eliminates the risk of expansiveness, facilitating the selection of foundation types. However, the presence of karstification in the carbonate rocks requires a detailed check of the existence of cavities before building, this being the most relevant geotechnical constraint for works in Sencelles.
