Estudio geotécnico in Costitx

Within the municipal term of Costitx, fine sands and silts predominate, accounting for more than half of the soil profiles, accompanied by a significant proportion of limestones, dolomites and marbles. These materials provide a variable bearing capacity: the sands and silts require verifying their compactness and possible presence of soft horizons before designing shallow foundations, whereas the limestones and carbonate rocks, when intact, allow direct foundations after checking their continuity. Permeability is associated with the presence of moderate aquifers, which may necessitate control of water discharge on site and special attention in transition zones between lithologies.

Seismic activity in Costitx is very low, with only a barely significant event recorded over 30 years and a maximum magnitude of 3.2, so seismicity does not represent a significant limitation for structural design. The municipality is located on calcareous domains, meaning there is potential for karstification: it is essential to analyse the presence of voids, dissolutions or cavities before selecting the foundation type, as this factor determines the greatest geotechnical uncertainty in the area. The non-clayey substrate rules out the risk of expansivity affecting shallow foundations.
