Estudio geotécnico in Valldemossa

In Valldemossa, the predominant ground is formed by fine sands and silts, which influences the bearing capacity of the soils and determines the choice of the most suitable foundation type. The occasional presence of gypsum, anhydrite and salts adds consideration of potential dissolution-related problems that may affect stability, particularly in areas where outcrops of limestones, dolomites and marbles are also identified. The formations detected tend to be of low permeability, with the possibility of hosting shallow aquifers, which may condition construction processes that require dewatering or deep excavations.

Seismicity in the municipality is very low, with a record of only one event in 30 years and a maximum magnitude of 2.5, so the seismic influence on the design is not significant. Nevertheless, the existence of karst-susceptible materials, especially in calcareous areas, requires thorough verification of the presence of karst cavities before founding, in order to avoid future risks of differential settlement. The non-clayey substratum rules out any swelling-related problems; the main geotechnical constraint is the potential for dissolutions and associated underground cavities linked to karst and gypsum.
