Estudio geotécnico in Palma

In Palma, deposits of fine sands and silts predominate, with a significant presence of carbonate formations such as limestones, dolomites and marbles, which directly influence the bearing capacity of the ground and the choice of the foundation model. Although there are occasional levels of gypsum, anhydrite and salts, which require special attention due to the potential risk of dissolution, the non-clayey substrate reduces the likelihood of problems associated with expansivity. The existence of aquifers, albeit with moderate permeability and yield, requires careful verification of the hydrogeological conditions during the geotechnical study.

The level of seismicity in Palma is very low, with only 1 significant event every 30 years and a low maximum magnitude, which minimises the requirements from the seismic standpoint in structural design. However, the frequent presence of carbonate formations implies the possible existence of karstification, so it is essential to investigate the presence of voids or cavities before executing any foundation. The main technical constraint for the geotechnical study in Palma will therefore be the assessment of karst development and the interaction with the soluble materials in the subsoil.
