Estudio geotécnico in Alhama de Granada

In Alhama de Granada, rocky substrata of phyllites and schists predominate, accompanied in smaller proportions by carbonate formations such as limestones, dolomites and marbles. These lithologies, in general, provide a good bearing capacity for shallow foundations, although their low permeability may influence the presence of superficial aquifers. It is important to note the occasional occurrence of muds and peats in deltaic environments; materials that are not very suitable as a foundation level due to their high compressibility.

The seismicity in this municipality is high, with 200 events recorded over 30 years and a maximum magnitude of 4.3, which requires a specific assessment in structural design to ensure safety in future construction. The presence of karstified ground, due to the limestones and dolomites, calls for a thorough geotechnical study to rule out the existence of cavities or unstable zones prior to any foundation. The non-clayey substratum rules out risks associated with expansiveness, with control of the karst and the seismic response being the main factors governing the geotechnical study in the area.
