Geotechnical study in Son Servera

In Son Servera, fine sands and silts predominate, accompanied by a significant proportion of gypsum, anhydrites and salts, as well as occasional occurrences of limestones, dolomites and marbles. This type of ground implies moderate bearing capacities, and particular attention should be paid to the dissolution risks associated with the gypsum and salts, which may affect stability in the medium and long term. The choice of foundation system must take into account the heterogeneity of the materials and verify that the foundation does not coincide with areas of soluble salts or soft materials.

Seismic activity in Son Servera shows a moderate frequency, with 24 events over 30 years and a maximum magnitude of 3.2, which implies a low requirement in terms of seismic design. However, the limestone environment makes it necessary to check for the possible presence of karst-related phenomena before executing any foundation works, as these can represent a serious constraint on safety and stability. The absence of a predominantly clayey ground rules out expansivity risk as the main conditioning factor; instead, karst verification and the dissolution of soluble materials are the elements with the greatest geotechnical influence in the area.
