Estudio geotécnico in Xàtiva

In Xàtiva, the predominant substrate is made up of limestones, dolomites and marbles, which favours the presence of soils with high bearing capacity. These materials are suitable for shallow foundations, provided that their level of alteration is verified and that no zones with significant fracturing are detected. In smaller proportion, fine sands, silts, compact gravels are observed and, occasionally, the occurrence of gypsum, anhydrite and salts, which may increase the risk of dissolution and differential settlements if they are affected by water. Overconsolidated clays and marls are uncommon and do not represent the main controlling factor in most cases.

Seismic activity in the municipality is classified as moderate, with 49 events recorded over the last thirty years and a maximum magnitude of 3.9, which imposes the usual requirements for seismic analysis in structural design. The presence of karstification in the carbonate formations is another relevant aspect: before defining the foundation type, it is essential to verify the existence of cavities or dissolution processes that could affect ground stability. As for expansivity, the predominance of a non-clayey substrate rules out risks associated with swelling. The main controlling factor in Xàtiva therefore lies in the detailed characterisation of the karst and the possible impact of gypsum to ensure geotechnical safety.
