Estudio geotécnico in Macael

In Macael, the geological substrate is made up mostly of slates and schists, accounting for 91% of the soils, with a residual presence of gypsum, anhydrite and salts. These lithologies generally provide adequate bearing capacity for shallow foundations, although their low permeability may favour the retention of water in shallow aquifers. It is important to consider the small proportion of soluble materials such as gypsum and salts, since their eventual dissolution can affect the long-term stability of foundations if they are located in these strata.

With regard to seismicity, Macael shows moderate seismic activity, with 12 events over 30 years and a maximum magnitude of 2.5, which implies a low structural risk from seismic movements in typical design. The non-clayey substrate rules out the problem of expansive soils; however, the potential presence of karst phenomena means that the existence of cavities or associated instabilities must be verified before carrying out any type of foundation. In this context, the fundamental technical constraint in Macael is the presence of karst and its prior control before the installation of structures.
